The default 128M vdev size used by zloop.sh isn't always large
enough and can result in ENOSPC failures which suspend the pool.
Increase the default size to 512M and provide a -s option which
can be used to specify an alternate size.
This does increase the free space requirements to run zloop.sh.
However, since the vdevs are sparse 4x the space is not required.

The portion of the zvol_replay_write() handler responsible for
replaying indirect log records for some reason never existed.
As a result indirect log records were not being correctly replayed.
This went largely unnoticed since the majority of zvol log records
were of the type WR_COPIED or WR_NEED_COPY prior to OpenZFS 7578.
This patch updates zvol_replay_write() to correctly handle these
log records and adds a new test case which verifies volume replay
to prevent any regression. The existing test case which verified
replay on filesystem was renamed slog_replay_fs.ksh for clarity.

OpenZFS provides a library called tpool which implements thread
pools for user space applications. Porting this library means
the zpool utility no longer needs to borrow the kernel mutex and
taskq interfaces from libzpool. This code was updated to use
the tpool library which behaves in a very similar fashion.
Porting libtpool was relatively straight forward and minimal
modifications were needed. The core changes were:
* Fully convert the library to use pthreads.
* Updated signal handling.
* lmalloc/lfree converted to calloc/free
* Implemented portable pthread_attr_clone() function.
Finally, update the build system such that libzpool.so is no
longer linked in to zfs(8), zpool(8), etc. All that is required
is libzfs to which the zcommon soures were added (which is the way
it always should have been). Removing the libzpool dependency
resulted in several build issues which needed to be resolved.
* Moved zfeature support to module/zcommon/zfeature_common.c
* Moved ratelimiting to to module/zfs/zfs_ratelimit.c
* Moved get_system_hostid() to lib/libspl/gethostid.c
* Removed use of cmn_err() in zcommon source
* Removed dprintf_setup() call from zpool_main.c and zfs_main.c
* Removed highbit() and lowbit()
* Removed unnecessary library dependencies from Makefiles
* Removed fletcher-4 kstat in user space

Add multihost=on|off pool property to control MMP. When enabled
a new thread writes uberblocks to the last slot in each label, at a
set frequency, to indicate to other hosts the pool is actively imported.
These uberblocks are the last synced uberblock with an updated
timestamp. Property defaults to off.
During tryimport, find the "best" uberblock (newest txg and timestamp)
repeatedly, checking for change in the found uberblock. Include the
results of the activity test in the config returned by tryimport.
These results are reported to user in "zpool import".
Allow the user to control the period between MMP writes, and the
duration of the activity test on import, via a new module parameter
zfs_multihost_interval. The period is specified in milliseconds. The
activity test duration is calculated from this value, and from the
mmp_delay in the "best" uberblock found initially.
Add a kstat interface to export statistics about Multiple Modifier
Protection (MMP) updates. Include the last synced txg number, the
timestamp, the delay since the last MMP update, the VDEV GUID, the VDEV
label that received the last MMP update, and the VDEV path. Abbreviated

Enable additional test cases, in most cases this required a few
minor modifications to the test scripts. In a few cases a real
bug was uncovered and fixed. And in a handful of cases where pools
are layered on pools the test case will be skipped until this is
supported. Details below for each test case.
* zpool_add_004_pos - Skip test on Linux until adding zvols to pools
is fully supported and deadlock free.
* zpool_add_005_pos.ksh - Skip dumpadm portion of the test which isn't
relevant for Linux. The find_vfstab_dev, find_mnttab_dev, and
save_dump_dev functions were updated accordingly for Linux. Add
O_EXCL to the in-use check to prevent the -f (force) option from
working for mounted filesystems and improve the resulting error.
* zpool_add_006_pos - Update test case such that it doesn't depend
on nested pools. Switch to truncate from mkfile to reduce space
requirements and speed up the test case.
* zpool_clear_001_pos - Speed up test case by filling filesystem to
25% capacity.
* zpool_create_002_pos, zpool_create_004_pos - Use sparse files for
file vdevs in order to avoid increasing the partition size.
* zpool_create_006_pos - 6ba1ce9 allows raidz+mirror configs with
similar redundancy. Updating the valid_args and forced_args cases.
* zpool_create_008_pos - Disable overlapping partition portion.
* zpool_create_011_neg - Fix to correctly create the extra partition.
Modified zpool_vdev.c to use fstat64_blk() wrapper which includes
the st_size even for block devices.
* zpool_create_012_neg - Updated to properly find swap devices.
* zpool_create_014_neg, zpool_create_015_neg - Updated to use
swap_setup() and swap_cleanup() wrappers which do the right thing
on Linux and Illumos. Removed '-n' option which succeeds under
Linux due to differences in the in-use checks.
* zpool_create_016_pos.ksh - Skipped test case isn't useful.
* zpool_create_020_pos - Added missing / to cleanup() function.
Remove cache file prior to test to ensure a clean environment
and avoid false positives.
* zpool_destroy_001_pos - Removed test case which creates a pool on
a zvol. This is more likely to deadlock under Linux and has never
been completely supported on any platform.
* zpool_destroy_002_pos - 'zpool destroy -f' is unsupported on Linux.
Mount point must not be busy in order to unmount them.
* zfs_destroy_001_pos - Handle EBUSY error which can occur with
volumes when racing with udev.
* zpool_expand_001_pos, zpool_expand_003_neg - Skip test on Linux
until adding zvols to pools is fully supported and deadlock free.
The test could be modified to use loop-back devices but it would
be preferable to use the test case as is for improved coverage.
* zpool_export_004_pos - Updated test case to such that it doesn't
depend on nested pools. Normal file vdev under /var/tmp are fine.
* zpool_import_all_001_pos - Updated to skip partition 1, which is
known as slice 2, on Illumos. This prevents overwriting the
default TESTPOOL which was causing the failure.
* zpool_import_002_pos, zpool_import_012_pos - No changes needed.
* zpool_remove_003_pos - No changes needed
* zpool_upgrade_002_pos, zpool_upgrade_004_pos - Root cause addressed
by upstream OpenZFS commit 3b7f360.
* zpool_upgrade_007_pos - Disabled in test case due to known failure.
Opened issue https://github.com/zfsonlinux/zfs/issues/6112
* zvol_misc_002_pos - Updated to to use ext2.
* zvol_misc_001_neg, zvol_misc_003_neg, zvol_misc_004_pos,
zvol_misc_005_neg, zvol_misc_006_pos - Moved to skip list, these
test case could be updated to use Linux's crash dump facility.
* zvol_swap_* - Updated to use swap_setup/swap_cleanup helpers.
File creation switched from /tmp to /var/tmp. Enabled minimal
useful tests for Linux, skip test cases which aren't applicable.

ZFS Test Suite Performance Regression Tests
This was pulled into OpenZFS via the compressed arc featureand was
separated out in zfsonlinux as a separate pull request from PR-4768.
It originally came in as QA-4903 in Delphix-OS from John Kennedy.
Expected Usage:
$ DISKS="sdb sdc sdd" zfs-tests.sh -r perf-regression.run
Porting Notes:
1. Added assertions in the setup script to make sure required tools
(fio, mpstat, ...) are present.
2. For the config.json generation in perf.shlib used arcstats and
other binaries instead of dtrace to query the values.
3. For the perf data collection:
- use "zpool iostat -lpvyL" instead of the io.d dtrace script
(currently not collecting zfs_read/write latency stats)
- mpstat and iostat take different arguments
- prefetch_io.sh is a placeholder that uses arcstats instead of
dtrace
4. Build machines require fio, mdadm and sysstat pakage (YMMV).
Future Work:
- Need a way to measure zfs_read and zfs_write latencies per pool.
- Need tools to takes two sets of output and display/graph the
differences
- Bring over additional regression tests from Delphix
This first phase brings over the ZFS SLM module, zfs_mod.c, to handle
auto operations in response to disk events. Disk event monitoring is
provided from libudev and generates the expected payload schema for
zfs_mod. This work leverages the recently added devid and phys_path
strings in the vdev label.

A port of the Illumos Crypto Framework to a Linux kernel module (found
in module/icp). This is needed to do the actual encryption work. We cannot
use the Linux kernel's built in crypto api because it is only exported to
GPL-licensed modules. Having the ICP also means the crypto code can run on
any of the other kernels under OpenZFS. I ended up porting over most of the
internals of the framework, which means that porting over other API calls (if
we need them) should be fairly easy. Specifically, I have ported over the API
functions related to encryption, digests, macs, and crypto templates. The ICP
is able to use assembly-accelerated encryption on amd64 machines and AES-NI
instructions on Intel chips that support it. There are place-holder
directories for similar assembly optimizations for other architectures
(although they have not been written).

Issue #4329
ZFS allows for specific permissions to be delegated to normal users
with the `zfs allow` and `zfs unallow` commands. In addition, non-
privileged users should be able to run all of the following commands:
* zpool [list | iostat | status | get]
* zfs [list | get]
Historically this functionality was not available on Linux. In order
to add it the secpolicy_* functions needed to be implemented and mapped
to the equivalent Linux capability. Only then could the permissions on
the `/dev/zfs` be relaxed and the internal ZFS permission checks used.
Even with this change some limitations remain. Under Linux only the
root user is allowed to modify the namespace (unless it's a private
namespace). This means the mount, mountpoint, canmount, unmount,
and remount delegations cannot be supported with the existing code. It
may be possible to add this functionality in the future.
This functionality was validated with the cli_user and delegation test
cases from the ZFS Test Suite. These tests exhaustively verify each
of the supported permissions which can be delegated and ensures only
an authorized user can perform it.
Two minor bug fixes were required for test-running.py. First, the
Timer() object cannot be safely created in a `try:` block when there
is an unconditional `finally` block which references it. Second,
when running as a normal user also check for scripts using the
both the .ksh and .sh suffixes.
Finally, existing users who are simulating delegations by setting
group permissions on the /dev/zfs device should revert that
customization when updating to a version with this change.

Add the ZFS Test Suite and test-runner framework from illumos.
This is a continuation of the work done by Turbo Fredriksson to
port the ZFS Test Suite to Linux. While this work was originally
conceived as a stand alone project integrating it directly with
the ZoL source tree has several advantages:
* Allows the ZFS Test Suite to be packaged in zfs-test package.
* Facilitates easy integration with the CI testing.
* Users can locally run the ZFS Test Suite to validate ZFS.
This testing should ONLY be done on a dedicated test system
because the ZFS Test Suite in its current form is destructive.
* Allows the ZFS Test Suite to be run directly in the ZoL source
tree enabled developers to iterate quickly during development.
* Developers can easily add/modify tests in the framework as
features are added or functionality is changed. The tests
will then always be in sync with the implementation.
Full documentation for how to run the ZFS Test Suite is available
in the tests/README.md file.
Warning: This test suite is designed to be run on a dedicated test
system. It will make modifications to the system including, but
not limited to, the following.
* Adding new users
* Adding new groups
* Modifying the following /proc files:
* /proc/sys/kernel/core_pattern
* /proc/sys/kernel/core_uses_pid
* Creating directories under /
Notes:
* Not all of the test cases are expected to pass and by default
these test cases are disabled. The failures are primarily due
to assumption made for illumos which are invalid under Linux.
* When updating these test cases it should be done in as generic
a way as possible so the patch can be submitted back upstream.
Most existing library functions have been updated to be Linux
aware, and the following functions and variables have been added.
* Functions:
* is_linux - Used to wrap a Linux specific section.
* block_device_wait - Waits for block devices to be added to /dev/.
* Variables: Linux Illumos
* ZVOL_DEVDIR "/dev/zvol" "/dev/zvol/dsk"
* ZVOL_RDEVDIR "/dev/zvol" "/dev/zvol/rdsk"
* DEV_DSKDIR "/dev" "/dev/dsk"
* DEV_RDSKDIR "/dev" "/dev/rdsk"
* NEWFS_DEFAULT_FS "ext2" "ufs"
* Many of the disabled test cases fail because 'zfs/zpool destroy'
returns EBUSY. This is largely causes by the asynchronous nature
of device handling on Linux and is expected, the impacted test
cases will need to be updated to handle this.
* There are several test cases which have been disabled because
they can trigger a deadlock. A primary example of this is to
recursively create zpools within zpools. These tests have been
disabled until the root issue can be addressed.
* Illumos specific utilities such as (mkfile) should be added to
the tests/zfs-tests/cmd/ directory. Custom programs required by
the test scripts can also be added here.
* SELinux should be either is permissive mode or disabled when
running the tests. The test cases should be updated to conform
to a standard policy.
* Redundant test functionality has been removed (zfault.sh).
* Existing test scripts (zconfig.sh) should be migrated to use
the framework for consistency and ease of testing.
* The DISKS environment variable currently only supports loopback
devices because of how the ZFS Test Suite expects partitions to
be named (p1, p2, etc). Support must be added to generate the
correct partition name based on the device location and name.
* The ZFS Test Suite is part of the illumos code base at:

When loading the ZFS kernel modules they should not populate the
spa namespace using the cache file. This behavior isn't consistent
with other Linux kernel modules and we need to move away from it.
Removing this makes the whole startup process predictable with four
basic steps which are driven by the init system.
1) modprobe
2) zpool import
3) zfs mount
4) zfs share
This change also helps lay the groundwork for eventually removing
the kobj_* compatibility code on the kernel side. It may need to
be preserved in userspace because libzfs_init() depends on it.
This is why the conditional must be wrapped with an #ifdef _KERNEL.

Issue #3063
This patch leverages Linux tracepoints from within the ZFS on Linux
code base. It also refactors the debug code to bring it back in sync
with Illumos.
The information exported via tracepoints can be used for a variety of
reasons (e.g. debugging, tuning, general exploration/understanding,
etc). It is advantageous to use Linux tracepoints as the mechanism to
export this kind of information (as opposed to something else) for a
number of reasons:
* A number of external tools can make use of our tracepoints
"automatically" (e.g. perf, systemtap)
* Tracepoints are designed to be extremely cheap when disabled
* It's one of the "accepted" ways to export this kind of
information; many other kernel subsystems use tracepoints too.
Unfortunately, though, there are a few caveats as well:
* Linux tracepoints appear to only be available to GPL licensed
modules due to the way certain kernel functions are exported.
Thus, to actually make use of the tracepoints introduced by this
patch, one might have to patch and re-compile the kernel;
exporting the necessary functions to non-GPL modules.
* Prior to upstream kernel version v3.14-rc6-30-g66cc69e, Linux
tracepoints are not available for unsigned kernel modules
(tracepoints will get disabled due to the module's 'F' taint).
Thus, one either has to sign the zfs kernel module prior to
loading it, or use a kernel versioned v3.14-rc6-30-g66cc69e or
newer.
Assuming the above two requirements are satisfied, lets look at an
example of how this patch can be used and what information it exposes
(all commands run as 'root'):
# list all zfs tracepoints available
$ ls /sys/kernel/debug/tracing/events/zfs
enable filter zfs_arc__delete
zfs_arc__evict zfs_arc__hit zfs_arc__miss
zfs_l2arc__evict zfs_l2arc__hit zfs_l2arc__iodone
zfs_l2arc__miss zfs_l2arc__read zfs_l2arc__write
zfs_new_state__mfu zfs_new_state__mru
# enable all zfs tracepoints, clear the tracepoint ring buffer
$ echo 1 > /sys/kernel/debug/tracing/events/zfs/enable
$ echo 0 > /sys/kernel/debug/tracing/trace
# import zpool called 'tank', inspect tracepoint data (each line was
# truncated, they're too long for a commit message otherwise)

For the specific tracepoint shown here, 'zfs_arc__miss', data is
exported detailing the arc_buf_hdr_t (hdr), blkptr_t (bp), and
zbookmark_t (zb) that caused the ARC miss (down to the exact DVA!).
This kind of precise and detailed information can be extremely valuable
when trying to answer certain kinds of questions.
For anybody unfamiliar but looking to build on this, I found the XFS
source code along with the following three web links to be extremely
helpful:
* http://lwn.net/Articles/379903/
* http://lwn.net/Articles/381064/
* http://lwn.net/Articles/383362/
I should also node the more "boring" aspects of this patch:
* The ZFS_LINUX_COMPILE_IFELSE autoconf macro was modified to
support a sixth paramter. This parameter is used to populate the
contents of the new conftest.h file. If no sixth parameter is
provided, conftest.h will be empty.
* The ZFS_LINUX_TRY_COMPILE_HEADER autoconf macro was introduced.
This macro is nearly identical to the ZFS_LINUX_TRY_COMPILE macro,
except it has support for a fifth option that is then passed as
the sixth parameter to ZFS_LINUX_COMPILE_IFELSE.
These autoconf changes were needed to test the availability of the Linux
tracepoint macros. Due to the odd nature of the Linux tracepoint macro
API, a separate ".h" must be created (the path and filename is used
internally by the kernel's define_trace.h file).
* The HAVE_DECLARE_EVENT_CLASS autoconf macro was introduced. This
is to determine if we can safely enable the Linux tracepoint
functionality. We need to selectively disable the tracepoint code
due to the kernel exporting certain functions as GPL only. Without
this check, the build process will fail at link time.
In addition, the SET_ERROR macro was modified into a tracepoint as well.
To do this, the 'sdt.h' file was moved into the 'include/sys' directory
and now contains a userspace portion and a kernel space portion. The
dprintf and zfs_dbgmsg* interfaces are now implemented as tracepoint as
well.

Make the style checker script accept right parentheses on their own
lines. This is motivated by the Linux tracepoints macro
DECLARE_EVENT_CLASS.
The code within TP_fast_assign() (a parameter of DECLARE_EVENT_CLASS)
is normal C assignments terminated by semicolons. But the style
checker forbids us from following a semicolon with a non-blank and
from preceding a right parenthesis with white space. Therefore the
closing parenthesis must go on the next line, yet the style checker
foribs us from indenting it for readability. Relaxing the
no-non-blank-after-semicolon rule would open the door to too many bad
style practices. So instead we relax the
no-white-space-before-right-paren rule if the parenthesis is on its
own line. The relaxation is overriden with the -p option so we still
have a way to catch misuse of this style.

The zimport.sh script makes use of the zpool-create.sh script
to construct test pools for importing with older versions of
ZoL. It is desirable to have a way to disable all the features
so new pools can be imported with older code.
The simplest and most flexible way to achieve this was to merge
the VERBOSE_FLAG and FORCE_FLAG in to a single ZPOOL_FLAGS
variable. The contents of this variable will be used in the
'zpool create' allowing us to easily pass arbitrary flags.

Several of the in-tree regression tests depend on the availability
of loop devices. If for some reason no loop devices are available
the tests will fail.
Normally this isn't an issue because most Linux distributions create
8 loop devices by default. This is enough for our purposes. However,
recent Fedora releases have only been creating a single loop device
and this leads to failures. Alternately, if something else of the
system is using the loop devices we may see failures.
The fix for this is to update the support scripts to dynamically
create loop devices as needed. The scripts need only create a node
under /dev/ and the loop driver with create the minor. This behavior
has been supported by the loop driver for ages.
Additionally this patch updates cleanup_loop_devices() to cleanup
loop devices which have already had their file store deleted. This
helps prevent stale loop devices from accumulating on the system due
to test failures.

zed monitors ZFS events. When a zevent is posted, zed will run any
scripts that have been enabled for the corresponding zevent class.
Multiple scripts may be invoked for a given zevent. The zevent
nvpairs are passed to the scripts as environment variables.
Events are processed synchronously by the single thread, and there is
no maximum timeout for script execution. Consequently, a misbehaving
script can delay (or forever block) the processing of subsequent
zevents. Plans are to address this in future commits.
Initial scripts have been developed to log events to syslog
and send email in response to checksum/data/io errors and
resilver.finish/scrub.finish events. By default, email will only
be sent if the ZED_EMAIL variable is configured in zed.rc (which is
serving as a config file of sorts until a proper configuration file
is implemented).

Issue #2
Verify that an assortment of known good reference pools can be imported
using different versions of the ZoL code.
By default references pools for the major ZFS implementation will be
checked against the most recent ZoL tags and the master development branch.
Alternate tags or branches may be verified with the '-s <src-tag> option.
Passing the keyword "installed" will instruct the script to test whatever
version is installed.
Preferentially a reference pool is used for all tests. However, if one
does not exist and the pool-tag matches one of the src-tags then a new
reference pool will be created using binaries from that source build.
This is particularly useful when you need to test your changes before
opening a pull request.
New reference pools may be added by placing a bzip2 compressed tarball
of the pool in the scripts/zpool-example directory and then passing
the -p <pool-tag> option. To increase the test coverage reference pools
should be collected for all the major ZFS implementations. Having these
pools easily available is also helpful to the developers.
Care should be taken to run these tests with a kernel supported by all
the listed tags. Otherwise build failure will cause false positives.
EXAMPLES:
The following example will verify the zfs-0.6.2 tag, the master branch,
and the installed zfs version can correctly import the listed pools.
Note there is no reference pool available for master and installed but
because binaries are available one is automatically constructed. The
working directory is also preserved between runs (-k) preventing the
need to rebuild from source for multiple runs.

Early versions of ZFS coordinated the creation and destruction
of device minors from userspace. This was inherently racy and
in late 2009 these ioctl()s were removed leaving everything up
to the kernel. This significantly simplified the code.
However, we never picked up these changes in ZoL since we'd
already significantly adjusted this code for Linux. This patch
aims to rectify that by finally removing ZFC_IOC_*_MINOR ioctl()s
and moving all the functionality down in to the kernel. Since
this cleanup will change the kernel/user ABI it's being done
in the same tag as the previous libzfs_core ABI changes. This
will minimize, but not eliminate, the disruption to end users.
Once merged ZoL, Illumos, and FreeBSD will basically be back
in sync in regards to handling ZVOLs in the common code. While
each platform must have its own custom zvol.c implemenation the
interfaces provided are consistent.
NOTES:
1) This patch introduces one subtle change in behavior which
could not be easily avoided. Prior to this change callers
of 'zfs create -V ...' were guaranteed that upon exit the
/dev/zvol/ block device link would be created or an error
returned. That's no longer the case. The utilities will no
longer block waiting for the symlink to be created. Callers
are now responsible for blocking, this is why a 'udev_wait'
call was added to the 'label' function in scripts/common.sh.
2) The read-only behavior of a ZVOL now solely depends on if
the ZVOL_RDONLY bit is set in zv->zv_flags. The redundant
policy setting in the gendisk structure was removed. This
both simplifies the code and allows us to safely leverage
set_disk_ro() to issue a KOBJ_CHANGE uevent. See the
comment in the code for futher details on this.
3) Because __zvol_create_minor() and zvol_alloc() may now be
called in a sync task they must use KM_PUSHPAGE.

Cstyle is the C source style checker used by Illumos. Since the
original ZFS source was written using these style guidelines they
must also be followed by ZoL for consistency.
The checker has been added to the scripts directory and may be
run on a per file basis. New patches should be careful to avoid
introducing new style warnings.
Additionally, the 'checkstyle' target has been added to the top
level Makefile and can be used to check the entire source tree.
While Zol has historically attempted to follow the SunOS style
guide the lack of a rigorous style checker has allowed various
warning to be introduced. Currently there are 2211 reported
style violations and we want to gradually eliminate these from
the tree.

One of the side effects of calling zvol_create_minors() in
zvol_init() is that all pools listed in the cache file will
be opened. Depending on the state and contents of your pool
this operation can take a considerable length of time.
Doing this at load time is undesirable because the kernel
is holding a global module lock. This prevents other modules
from loading and can serialize an otherwise parallel boot
process. Doing this after module inititialization also
reduces the chances of accidentally introducing a race
during module init.
To ensure that /dev/zvol/<pool>/<dataset> devices are
still automatically created after the module load completes
a udev rules has been added. When udev notices that the
/dev/zfs device has been create the 'zpool list' command
will be run. This then will cause all the pools listed
in the zpool.cache file to be opened.
Because this process in now driven asynchronously by udev
there is the risk of problems in downstream distributions.

The new snapdev dataset property may be set to control the
visibility of zvol snapshot devices. By default this value
is set to 'hidden' which will prevent zvol snapshots from
appearing under /dev/zvol/ and /dev/<dataset>/. When set to
'visible' all zvol snapshots for the dataset will be visible.
This functionality was largely added because when automatic
snapshoting is enabled large numbers of read-only zvol snapshots
will be created. When creating these devices the kernel will
attempt to read their partition tables, and blkid will attempt
to identify any filesystems on those partitions. This leads
to a variety of issues:
1) The zvol partition tables will be read in the context of
the `modprobe zfs` for automatically imported pools. This
is undesirable and should be done asynchronously, but for
now reducing the number of visible devices helps.
2) Udev expects to be able to complete its work for a new
block devices fairly quickly. When many zvol devices are
added at the same time this is no longer be true. It can
lead to udev timeouts and missing /dev/zvol links.
3) Simply having lots of devices in /dev/ can be aukward from
a management standpoint. Hidding the devices your unlikely
to ever use helps with this. Any snapshot device which is
needed can be made visible by changing the snapdev property.
NOTE: This patch changes the default behavior for zvols which
was effectively 'snapdev=visible'.

Test 5, 6, 7, and 7 in zconfig.sh use /bin/ as a source of random

To resolve this issue we create a somewhat random collection of
