Add zfs_prepare_disk script for disk firmware install
Have libzfs call a special `zfs_prepare_disk` script before a disk is
included into the pool.  The user can edit this script to add things
like a disk firmware update or a disk health check.  Use of the script
is totally optional. See the zfs_prepare_disk manpage for full details.

status: report pool suspension state under failmode=continue
When failmode=continue is set and the pool suspends, both 'zpool status'
and the 'zfs/pool/state' kstat ignore it and report the normal vdev tree
state. There's no clear indicator that the pool is suspended. This is
unlike suspend in failmode=wait, or suspend due to MMP check failure,
which both report "SUSPENDED" explicitly.

This commit changes it so SUSPENDED is reported for failmode=continue
the same as for other modes.

Rationale:

The historical behaviour of failmode=continue is roughly, "press on as
though all is well". To this end, the fact that the pool had suspended
was not shown, to maintain the façade that all is well.

Its unclear why hiding this information was considered appropriate. One
possibility is that it was expected that a true pool fault would always
be reported as DEGRADED or FAULTED, and that the pool could not suspend
without these happening.

That is not necessarily true, as vdev health and suspend state are only
loosely connected, such that a pool in (apparent) good health can be
suspended for good reasons, and of course a degraded pool does not lead
to suspension. Even if that expectation were true, there's still a
difference in urgency - a degraded pool may not need to be attended to
for hours, while a suspended pool is most often unusable until an
operator intervenes.

An operator that has set failmode=continue has presumably done so
because their workload is one that can continue to operate in a useful
way when the pool suspends. In this case the operator still needs a
clear indicator that there is a problem that needs attending to.

Fix occasional rsend test crashes
We have occasional crashes in the rsend tests. Debugging revealed 
that this is because the send_worker thread is getting EINTR from 
splice(). This happens when a non-fatal signal is received during 
the syscall. We should retry the syscall, rather than exiting failure.
Tweak the loop to only break if the splice is finished or we receive 
a non-EINTR error.

ZIL: Fix potential race on flush deferring.
zil_lwb_set_zio_dependency() can not set write ZIO dependency on
previous LWB's write ZIO if one is already in done handler and set
state to LWB_STATE_WRITE_DONE.  So theoretically done handler of
next LWB's write ZIO may run before done handler of previous LWB
write ZIO completes.  In such case we can not defer flushes, since
the flush issue process is not locked.

This may fix some reported assertions of lwb_vdev_tree not being
empty inside zil_free_lwb().

c63aabaf1c Improve the handling of sharesmb,sharenfs properties
For sharesmb and sharenfs properties, the status of setting the
property is tied with whether we succeed to share the dataset or
not. In case sharing the dataset is not successful, this is
treated as overall failure of setting the property. In this case,
if we check the property after the failure, it is set to on.

This commit updates this behavior and the status of setting the
share properties is not returned as failure, when we fail to
share the dataset.

For sharenfs property, if access list is provided, the syntax
errors in access list/host adresses are not validated until after
setting the property during postfix phase while trying to
share the dataset. This is not correct, since the property has
already been set when we reach there.

Syntax errors in access list/host addresses are validated while
validating the property list, before setting the property and
failure is returned to user in this case when there are errors
in access list.

bbac1d2977 Update the behavior of mountpoint property
There are some inconsistencies in the handling of mountpoint
property. This commit updates the behavior and makes it
consistent.

If mountpoint property is set when dataset is unmounted, this
would update the mountpoint property. The mountpoint could be
valid or invalid in this case. Setting the mountpoint property
would result in success in this case. Dataset would still be
unmounted here.

On the other hand, if dataset is mounted and mountpoint
property is updated to something invalid where mount cannot be
successful, for example, setting the mountpoint inside a readonly
directory. This would unmount the dataset, set the mountpoint
property to requested value and tries to mount the dataset. The
mount operation returns error and this error is treated as
overall failure of setting the property while the property is
actually set.

To make the behavior consistent in case dataset is mounted or
unmounted, we should try to mount the dataset whenever mountpoint
property is updated. This would result in mounting the datasets
if canmount property is set to on, regardless if the dataset was
previously unmounted.

The failure in mount operation while setting the mountpoint
property should not be treated as failure, since the property is
actually set now to user requested value.

cmd: add 'help' subcommand to zpool and zfs
'program help subcommand' is a reasonably common pattern for
multifunction command-line programs. This commit adds support for that
style to the zpool and zfs commands.

When run as 'zpool help [<topic>]' or 'zfs help [<topic>]', executes the
'man' program on the PATH with the most likely manpage name for the
requested topic: "zpool-<topic>" or "zfs-<topic>" for subcommands, or
"zpool<topic>" or "zfs<topic>" for the "concepts" and "props" topics.
If no topic is supplied, uses the top "zpool" or "zfs" pages.

 - Block size must be power-of-2 if destination offset != 0, since
there can be no multiple blocks of non-power-of-2 size.

The first should handle the case when destination file has several
blocks but still is not bigger than one block of the source file.
The second fixes panic in dmu_buf_hold_array_by_dnode() on attempt
to concatenate files with equal but non-power-of-2 block sizes.

Increase limit of redaction list by using spill block
Currently redaction bookmarks and their associated redaction lists
have a relatively low limit of 36 redaction snapshots. This is imposed
by the number of snapshot GUIDs that fit in the bonus buffer of the
redaction list object. While this is more than enough for most use
cases, there are some limited cases where larger numbers would be
useful to support.

We tweak the redaction list creation code to use a spill block if
the number of redaction snapshots is above the amount that would fit
in the bonus buffer. We also make a small change to allow spill blocks
to be use for types of data besides SA. In order to fully leverage

Avoid save/restoring AMX registers to avoid a SPR erratum
Intel SPR erratum SPR4 says that if you trip into a vmexit while
doing FPU save/restore, your AMX register state might misbehave...
and by misbehave, I mean save all zeroes incorrectly, leading to
explosions if you restore it.

Since we're not using AMX for anything, the simple way to avoid
this is to just not save/restore those when we do anything, since
we're killing preemption of any sort across our save/restores.

If we ever decide to use AMX, it's not clear that we have any
way to mitigate this, on Linux...but I am not an expert.

tests/block_cloning: rename and document get_same_blocks helper
`get_same_blocks` is a helper to compare two files and return a list of
the blocks that are clones of each other. Its very necessary for block
cloning tests.

Previously it was incorrectly called `unique_blocks`, which is the
_inverse_ of what it does (an early version did list unique blocks; it
was changed but the name was not). So if nothing else, it should be
called `duplicate_blocks`.

But, keeping the details of a clone operation in your head is actually
quite difficult, without the additional overhead of wondering how the
tools work. So I've renamed it to better describe what it does, added a
usage note, and changed it to return block indexes from 0 instead of 1,
to match how L0 blocks are normally counted.

Update outdated assertion from zio_write_compress
As part of some internal gang block testing within Delphix
we hit the assertion removed by this patch. The assertion
was triggered by a ZIO that had two copies and was a gang
block making the following expression equal to 3:
```
MIN(zp->zp_copies + BP_IS_GANG(bp), spa_max_replication(spa))
```
and failing when we expected the above to be equal to
`BP_GET_NDVAS(bp)`.

The assertion is no longer valid since the following commit:
```

```

The above commit changed gang block headers so they can't
have more than 2 copies but the assertion in question from
this PR was never updated.

ZIL: Second attempt to reduce scope of zl_issuer_lock.
The previous patch #14841 appeared to have significant flaw, causing
deadlocks if zl_get_data callback got blocked waiting for TXG sync.  I
already handled some of such cases in the original patch, but issue
 #14982 shown cases that were impossible to solve in that design.

This patch fixes the problem by postponing log blocks allocation till
the very end, just before the zios issue, leaving nothing blocking after
that point to cause deadlocks.  Before that point though any sleeps are
now allowed, not causing sync thread blockage.  This require slightly
more complicated lwb state machine to allocate blocks and issue zios
in proper order.  But with removal of special early issue workarounds
the new code is much cleaner now, and should even be more efficient.

Since this patch uses null zios between write, I've found that null
zios do not wait for logical children ready status in zio_ready(),
that makes parent write to proceed prematurely, producing incorrect
log blocks.  Added ZIO_CHILD_LOGICAL_BIT to zio_wait_for_children()
fixes it.

ZIL: Replay blocks without next block pointer.
If we get next block allocation error during log write, we trigger
transaction commit.  But the block we have just completed is still
written and transactions it covers will be acknowledged normally.
If after that we ignore the block during replay just because it is
the last in the chain, we may not replay some transactions that we
have acknowledged as synced, that is not right.

To save some CPU time use dmu_buf_hold_noread*() in z*_get_data()
and explicitly call dbuf_read() in dmu_sync_late_arrival(). There
is also a chance that by that time TXG will already be synced and
we won't have to do it at all.

Linux 6.5 compat: replace generic_file_splice_read with filemap_splice_read
The generic_file_splice_read function was removed in Linux 6.5 in favor
of filemap_splice_read. Add an autoconf test for filemap_splice_read and
use it if it is found as the handler for .splice_read in the
file_operations struct. Additionally, ITER_PIPE was removed in 6.5. This
change removes the ITER_* macros that OpenZFS doesn't use from being
tested in config/kernel-vfs-iov_iter.m4. The removal of ITER_PIPE was
causing the test to fail, which also affected the code responsible for
setting the .splice_read handler, above. That behavior caused run-time
panics on Linux 6.5.

linux/spl/kmem_cache: undefine kmem_cache_alloc before defining it
When compiling a kernel with bcachefs and zfs,
the two macros will collide, making it impossible
to have both filesystems.

It is sufficient to just undefine the macro before calling it.

On why this should be in ZFS rather than bcachefs, currently,
bcachefs is not a in-tree filesystem, but,
it has a reasonably high chance of getting included soon.

This avoids the breakage in ZFS early,
this patch may be distributed downstream in NixOS
and is already used there.
