Don Brady db75854cbb zed syslog entries drop important info
ZED will log zevents summaries to the syslog, however the log entries 
tend to drop event details that can be useful for diagnosis. This is 
especially true for ereport events, like io, checksum, and delay.

Update the all-syslog.sh script to log additional event information.

Add an optional config option, ZED_SYSLOG_DISPLAY_GUIDS, to zed.rc
for choosing GUIDs over names for pool and vdev.

Change the default ZED_SYSLOG_SUBCLASS_EXCLUDE to exclude history_event 
events. These events tend to be frequent, convey no meaningful info, 
and are already logged in the zpool history.

Don Brady b3f4436d37 Ignore special vdev ashift for spa ashift min/max
The removal of a vdev in the normal class would fail if there was a
special or deup vdev that had a different ashift than the vdevs in
the normal class.

Moved the initialization of spa_min_ashift / spa_max_ashift from
vdev_open so that it occurs after the vdev allocation bias was
initialized (i.e. after vdev_load).

Caveat -- In order to remove a special/dedup vdev it must have the
same ashift as the normal pool vdevs.  This could perhaps be lifted
in the future (i.e. for the case where there is ample space in any
surviving special class vdevs)

Ryan Moeller 725c9e22ca Cross-platform acltype
The acltype property is currently hidden on FreeBSD and does not
reflect the NFSv4 style ZFS ACLs used on the platform.  This makes it
difficult to observe that a pool imported from FreeBSD on Linux has a
different type of ACL that is being ignored, and vice versa.

Add an nfsv4 acltype and expose the property on FreeBSD.

Make the default acltype nfsv4 on FreeBSD.

Setting acltype to an unhanded style is treated the same as setting
it to off.  The ACLs will not be removed, but they will be ignored.

Warner Losh faa62966b1 aarch64: Use proper guards for NEON instructions
The zstd code assumes that if you are on aarch64, you have NEON
instructions. This is not necessarily true. In a boot loader, where
you might not have the VFP properly initialized, these instructions
may not be available. It's also an error to include arm_neon.h when
the NEON insturctions aren't enabled. Change the guards for using the
NEON instructions from __aarch64__ to __ARM_NEON which is the standard
symbol for knowing if they are available.

__ARM_NEON is the proper symbol, defined in ARM C Language Extensions
Release 2.1 (https://developer.arm.com/documentation/ihi0053/d/). Some
sources suggest __ARM_NEON__, but that's the obsolete spelling from
prior versions of the standard.

Updated based on zstd pull request https://github.com/facebook/zstd/pull/2356

Ryan Moeller a51019f4ec FreeBSD: Improve libzfs_error_init messages
It is a common mistake to have failed to autoload the module due to
permission issues when running a ZFS command as a user.  "Operation
not permitted" is an unhelpfully vague error message.

Use a thread-local message buffer to format a nicer error message.
We can infer that loading the kernel module failed if the module is
not loaded.  This can be extended with heuristics for other errors
in the future.

While looking at this stuff, remove an unused thread-local message
buffer found in libspl and remove some inaccurate verbiage from the
comment on libzfs_load_module.

can be released from memory pool.

Right now with regular use, the pool is checked for old objects on each
allocation attempt from this pool. so basically polling by its use. Now
consider what happens if someone writes a lot of files and stops use of
the volume or even unmounts it. So the code will no longer check if
objects can be released from the pool. Already allocated objects will
still stay in pool cache. this is no big issue for common use. But

The consequence of this is that the "stack_frame_non_standard"

incorrectly which results in a build failure.  This change adds
the appropriate header to the "objtool" check so it now behaves

Adam D. Moss edd23dba81 Add DB_RF_NOPREFETCH to dbuf_read()s in dnode.c
Prefetching of dnodes in dbuf_read() can cause significant mutex
contention for some workloads and isn't very helpful.  This is
because we already get 32 dnodes for each block read, and when
iterating over a directory we prefetch the dnodes in the directory.
Disable this prefetching to prevent the lock contention.

Brian Behlendorf 7b353d2c8c Fix PREEMPTION=y and BLK_CGROUP=y config on arm64
With PREEMPTION=y and BLK_CGROUP=y preempt_schedule_notrace() is being
used on arm64 which is a GPL-only function and hence the build of the
DKMS kernel module fails.

Fix that by redefining preempt_schedule_notrace() to preempt_schedule()
which should be safe as long as tracing is not used.

Ryan Moeller d8a81c3d3c FreeBSD: Code cleanup in zio_crypt
Address some unused value and control flow issues flagged by Coverity.

Unreachable code is pruned and unused values are avoided.
Some scattered sections are reordered for coherence.

We can assume kmem_alloc(n, KM_SLEEP) doesn't fail, so there is no need
to check if it returned NULL.  The allocated memory doesn't need to be
zeroed, other than the last iovec (the MAC).

George Wilson 626abe164d zpool command complains about /etc/exports.d
If the /etc/exports.d directory does not exist, then we should only
create it when we're performing an action which already requires root
privileges.

This commit moves the directory creation to the enable/disable code
path which ensures that we have the appropriate privileges.
