Despite that dracut has a hard dependency on bash,
its modules doesn't, dracut only has a hard dependency on bash for
module-setup (on a fully usable machine). Inside initramfs, dracut
allows users choose from a list of handful other shells, e.g. bash,
busybox, dash, mkfsh.
In fact, my local machine's initramfs is being built with dash,
and it's functional for a very long time.
Before 64025fa3a (Silence 'make checkbashisms', 2020-08-20), we also
allows our users to have that right, too.
Let's fix the problem 'make checkbashisms' reported and allows our users
to have that right, again.
For 'plymouth' case, let's simply run the command inside the if instead
of checking for the existence of command before running it, because the
status is also failture if plymouth is unavailable.
While we're at it, let's remove an unnecessary fork for grep in
zfs-generator.sh.in and its following complicated 'if elif fi' with
a simple 'case ... esac'.
To support this change, also exclude 90zfs from "make checkbashisms"
because the current CI infrastructure ships an old version of
"checkbashisms", which complains about "command -v", while the current
latest "checkbashisms" thinks it's fine. In the near future, we can
revert that change to "Makefile.am" when CI infrastructure is updated.

Investigating influence of scrub (especially sequential) on random read
latency I've noticed that on some HDDs single 4KB read may take up to 4
seconds! Deeper investigation shown that many HDDs heavily prioritize
sequential reads even when those are submitted with queue depth of 1.
This patch addresses the latency from two sides:
- by using _min_active queue depths for non-interactive requests while
the interactive request(s) are active and few requests after;
- by throttling it further if no interactive requests has completed
while configured amount of non-interactive did.
While there, I've also modified vdev_queue_class_to_issue() to give
more chances to schedule at least _min_active requests to the lowest
priorities. It should reduce starvation if several non-interactive
processes are running same time with some interactive and I think should
make possible setting of zfs_vdev_max_active to as low as 1.
I've benchmarked this change with 4KB random reads from ZVOL with 16KB
block size on newly written non-fragmented pool. On fragmented pool I
also saw improvements, but not so dramatic. Below are log2 histograms
of the random read latency in milliseconds for different devices:
4 2x mirror vdevs of SATA HDD WDC WD20EFRX-68EUZN0 before:
0, 0, 2, 1, 12, 21, 19, 18, 10, 15, 17, 21
after:
0, 0, 0, 24, 101, 195, 419, 250, 47, 4, 0, 0
, that means maximum latency reduction from 2s to 500ms.
4 2x mirror vdevs of SATA HDD WDC WD80EFZX-68UW8N0 before:
0, 0, 2, 31, 38, 28, 18, 12, 17, 20, 24, 10, 3
after:
0, 0, 55, 247, 455, 470, 412, 181, 36, 0, 0, 0, 0

after:
0, 0, 0, 0, 0, 0, 0, 0, 283, 92351, 34844, 90
I've also measured scrub time during the test and on idle pools. On
idle fragmented pool I've measured scrub getting few percent faster
due to use of QD3 instead of QD2 before. On idle non-fragmented pool
I've measured no difference. On busy non-fragmented pool I've measured
scrub time increase about 1.5-1.7x, while IOPS increase reached 5-9x.

Furthermore, the SPA_LOAD_NONE check in vdev_dtl_contains() leads to an

On systems with musl libc, hostid(1) always prints "00000000", which
will cause improper behavior when the 90zfs module is configured in a
dracut initramfs. Work around this by copying the host /etc/hostid if
the file exists, and otherwise only write /etc/hostid if hostid(1)
returns something meaningful. This avoids zgenhostid creating a random
/etc/hostid for the initramfs, which could lead to errors when trying to
import the pool if spl_hostid isn't defined in the kernel command line.
Furthermore, tag the /etc/hostid file as hostonly, since it is system
specific and shouldn't be taken into account when trying to use an
initramfs generated in one system to boot into a different system.

A common usage pattern for zgenhostid, including in the ZFS dracut
module, is running it as:
zgenhostid $(hostid)
However, zgenhostid only accepted hostid arguments greater than 0, which
meant that, when the output of hostid(1) was "00000000", zgenhostid
would error out, even though 0 is a possible return value for the
gethostid(3) function used by hostid(1):
- On current musl libc, gethostid(3) is a stub that always returns 0.
- On glibc, gethostid(3) will return 0 if /etc/hostid exists but is
smaller than 4 bytes.
In these cases, it makes more sense for zgenhostid to treat a value of 0
as other parts of the zfs codebase do, meaning that a hostid value
couldn't be determined; therefore, it should attempt to generate a
random value to write into /etc/hostid.
The manpage and usage output have been updated to reflect this.
Whitespace has also been fixed in the usage output.

This patch adds a new top-level vdev type called dRAID, which stands
for Distributed parity RAID. This pool configuration allows all dRAID
vdevs to participate when rebuilding to a distributed hot spare device.
This can substantially reduce the total time required to restore full
parity to pool with a failed device.
A dRAID pool can be created using the new top-level `draid` type.
Like `raidz`, the desired redundancy is specified after the type:
`draid[1,2,3]`. No additional information is required to create the
pool and reasonable default values will be chosen based on the number
of child vdevs in the dRAID vdev.
zpool create <pool> draid[1,2,3] <vdevs...>
Unlike raidz, additional optional dRAID configuration values can be
provided as part of the draid type as colon separated values. This
allows administrators to fully specify a layout for either performance
or capacity reasons. The supported options include:
zpool create <pool> \
draid[<parity>][:<data>d][:<children>c][:<spares>s] \
<vdevs...>
- draid[parity] - Parity level (default 1)
- draid[:<data>d] - Data devices per group (default 8)
- draid[:<children>c] - Expected number of child vdevs
- draid[:<spares>s] - Distributed hot spares (default 0)

-K draid|raidz|random - kind of RAID to test
-D <value> - dRAID data drives per group

-R <value> - RAID parity (raidz or dRAID)

ZFS channel programs (invoked by `zfs program`) are executed in a LUA
sandbox with a limit on the amount of memory they can consume. The
limit is 10MB by default, and can be raised to 100MB with the `-m` flag.
If the memory limit is exceeded, the LUA program exits and the command
fails with a message like `Channel program execution failed: Memory
limit exhausted.`
The LUA sandbox allocates memory with `vmem_alloc(KM_NOSLEEP)`, which
will fail if the requested memory is not immediately available. In this
case, the program fails with the same message, `Memory limit exhausted`.
However, in this case the specified memory limit has not been reached,
and the memory may only be temporarily unavailable.
This commit changes the LUA memory allocator `zcp_lua_alloc()` to use
`vmem_alloc(KM_SLEEP)`, so that we won't spuriously fail when memory is
temporarily low. Instead, we rely on the system to be able to free up
memory (e.g. by evicting from the ARC), and we assume that even at the
highest memory limit of 100MB, the channel program will not truly
exhaust the system's memory.

This shows up when compiling freebsd-head on amd64 using gcc-6.4.
The lib32 compat build ends up tripping over this assumption.

Closes#11098
Remove reference to EFI(?), explain that the new space
is beyond the GPT for whole-disk vdevs, and add section noting how it
behaves with partition vdevs in terms of how the user is most likely to
encounter it ‒ the previous phrasing was confusing
and seemed to indicate that "zpool online -e" will be able to claim
GPT[whatever, ZFS, free space, whatever]
into
GPT[whatever, ZFS, whatever]
but that's not the case, as it'll only be able to do so after manually
resizing the ZFS partition to include the free space beforehand, i.e.:
GPT[whatever, ZFS, free space, whatever]
GPT[whatever, [ZFS + free space], potentially left-overs, whatever]
# zpool online -e
GPT[whatever, ZFS, whatever]

The copy_exec() function expects that the full path of the target
file is passed rather than just the directory, and will take care
of creating the underlying directories if they don't exist.

We can consolidate the unlocking procedure into one place by starting
with drop_suspend set to B_FALSE and moving the open count check up.
While here, a little code cleanup. Match the out labels between
zvol_geom_open and zvol_cdev_open, and add a missing period in some
comments.

zvol_first_open can fail with EINTR if spa_namespace_lock is not held
and cannot be taken without waiting.
Apply the same logic that was done for zvol_geom_open to take
spa_namespace_lock if not already held on first open in zvol_cdev_open.
