Bassu 7a4f54688e Explain 'zfs list -t snap -o name -s name' speedup
Commit 0cee240 from FreeBSD dramatically speeds up 'zfs list'
performance assuming you're only interested in the dataset
names.  This optimization should be mentioned in the man page
to allow end users to take advantage of it.

Matthew Thode 760ec997df Updating init scripts to have more robust grepping
The previous pattern could accidentally match on things like
'real_root=ZFS=node02-zp00/ROOT/rootfs' due to the 'ZFS=no'
substring.

Tim Chase fd4f76160c Handle concurrent snapshot automounts failing due to EBUSY.
In the current snapshot automount implementation, it is possible for
multiple mounts to attempted concurrently.  Only one of the mounts will
succeed and the other will fail.  The failed mounts will cause an EREMOTE
to be propagated back to the application.

This commit works around the problem by adding a new exit status,
MOUNT_BUSY to the mount.zfs program which is used when the underlying
mount(2) call returns EBUSY.  The zfs code detects this condition and
treats it as if the mount had succeeded.

Massimo Maggi b695c34ea4 Honor CONFIG_FS_POSIX_ACL kernel option
The required Posix ACL interfaces are only available for kernels
with CONFIG_FS_POSIX_ACL defined.  Therefore, only enable Posix
ACL support for these kernels.  All major distribution kernels
enable CONFIG_FS_POSIX_ACL by default.

If your kernel does not support Posix ACLs the following warning
will be printed at ZFS module load time.

  "ZFS: Posix ACLs disabled by kernel"

Brian Behlendorf 2517c8ee08 Switch allocations from KM_SLEEP to KM_PUSHPAGE
A couple of kmem_alloc() allocations were using KM_SLEEP in
the sync thread context.  These were accidentally introduced
by the recent set of Illumos patches.  The solution is to
switch to KM_PUSHPAGE.

dsl_dataset_promote_sync() -> promote_hold() -> snaplist_make() ->
kmem_alloc(sizeof (*snap), KM_SLEEP);

dsl_dataset_user_hold_sync() -> dsl_onexit_hold_cleanup() ->
kmem_alloc(sizeof (*ca), KM_SLEEP)

Porting notes:

1. zfs_dbgmsg_print() is only used in userland. Since we do not have
   mdb on Linux, it does not make sense to make it available in the
   kernel. This means that a build failure will occur if any future
   kernel patch depends on it. However, that is unlikely given that
   this functionality was added to support zdb.

2. zfs_dbgmsg_print() is only invoked for -VVV or greater log levels.
   This preserves the existing behavior of minimal noise when running
   with -V, and -VV.

3. In vdev_config_generate() the call to nvlist_alloc() was not
   changed to fnvlist_alloc() because we must pass KM_PUSHPAGE in
   the txg_sync context.

The /proc/self/cmd watchpoint interface is specific to Solaris.
Therefore, the #3113 implementation was reworked to use the more
portable mprotect(2) system call.  When the pages are watched they
are marked read-only for protection.  Any write to the protected
address range immediately trigger a SIGSEGV.  The pages are marked
writable again when they are unwatched.

Porting notes:

1. 13fe019870 introduced a merge conflict
   in dsl_dataset_user_release_tmp where some variables were moved
   outside of the preprocessor directive.

2. dea9dfefdd747534b3846845629d2200f0616dad made the previous merge
   conflict worse by switching KM_SLEEP to KM_PUSHPAGE. This is notable
   because this commit refactors the code, adding a new KM_SLEEP
   allocation. It is not clear to me whether this should be converted
   to KM_PUSHPAGE.

3. We had a merge conflict in libzfs_sendrecv.c because of copyright
   notices.

4. Several small C99 compatibility fixed were made.

Porting Notes:

1. The alignment assumptions for the tx_cpu structure assume that
   a kmutex_t is 8 bytes.  This isn't true under Linux but tc_pad[]
   was adjusted anyway for consistency since this structure was
   never carefully aligned in ZoL.  If careful alignment does impact
   performance significantly this should be reworked to be portable.

Porting notes:

1. include/sys/zfs_context.h has been modified to render some new
   macros inert until dtrace is available on Linux.

2. Linux-specific changes have been adapted to use SET_ERROR().

3. I'm NOT happy about this change.  It does nothing but ugly
   up the code under Linux.  Unfortunately we need to take it to
   avoid more merge conflicts in the future.  -Brian

Porting Notes:

1. The patch was restructured to take advantage of the existing
   spa statistics infrastructure.  To accomplish this the kstat
   was moved in to spa->io_stats and the init/destroy code moved
   to spa_stats.c.

2. The I/O kstat was simply named <pool> which conflicted with the
   pool directory we had already created.  Therefore it was renamed
   to <pool>/io

3. An update handler was added to allow the kstat to be zeroed.

Porting notes:

1. ZFSOnLinux had already addressed many of these issues because of
   its use of -Wall. However, the manner in which they were addressed
   differed. The illumos fixes replace the ones previously made in
   ZFSOnLinux to reduce code differences.

2. Part of the upstream patch made a small change to arc.c that might
   address zfsonlinux/zfs#1334.

3. The initialization of aclsize in zfs_log_create() differs because
   vsecp is a NULL pointer on ZFSOnLinux.

4. The changes to zfs_register_callbacks() were dropped because it
   has diverged and needs to be resynced.

Brian Behlendorf a35beedfb3 Add cstyle.pl utility and cstyle.1 man page
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.

Note the cstyle.1 man page is provided under man/man1/cstyle.1
but since it is a developer utility it is not installed along
with the other man pages.
