Traditionally, unused dentries would be cached in the dentry cache until
the associated entry is no longer on disk. The cached dentry continues
to hold an inode reference, causing the inode to be pinned (see previous
commit).
Here we implement the dentry op d_delete, which is roughly analogous to
the drop_inode superblock op, and add a zfs_delete_dentry tunable to
control its behaviour. By default it continues the traditional
behaviour, but when the tunable is enabled, we signal that an unused
dentry should be freed immediately, releasing its inode reference, and
so allowing that inode to be deleted if no longer in use.

A single slow responding disk can affect the overall read
performance of a raidz group. When a raidz child disk is
determined to be a persistent slow outlier, then have it
sit out during reads for a period of time. The raidz group
can use parity to reconstruct the data that was skipped.
Each time a slow disk is placed into a sit out period, its
`vdev_stat.vs_slow_ios count` is incremented and a zevent
class `ereport.fs.zfs.delay` is posted.
The length of the sit out period can be changed using the
`raid_read_sit_out_secs` module parameter. Setting it to
zero disables slow outlier detection.

When destroying a zvol, it is not "unpublished" from the system (that
is, /dev/zd* node removed) until zvol_os_free(). Under Linux, at the
time del_gendisk() and put_disk() are called, the device node may still
be have an active hold, from a userspace program or something inside the
kernel (a partition probe). As it is currently, this can lead to calls
to zvol_open() or zvol_release() while the zvol_state_t is partially or
fully freed. zvol_open() has some protection against this by checking
that private_data is NULL, but zvol_release does not.
This implements a better ordering for all of this by adding a new
OS-side method, zvol_os_remove_minor(), which is responsible for fully
decoupling the "private" (OS-side) objects from the zvol_state_t. For
Linux, that means calling put_disk(), nulling private_data, and freeing
zv_zso.
This takes the place of zvol_os_clear_private(), which was a nod in that
direction but did not do enough, and did not do it early enough.
Equivalent changes are made on the FreeBSD side to follow the API
change.

will require, it can use new metaslab_alloc_range() function to

improve space efficiency by allocating bigger LWBs on RAIDZ/dRAID
instead of padding and possibly packing more ZIL records there.
It may also allow to reduce ganging in some cases by allowing to
allocate smaller LWBs when we are not sure we'll need bigger.
On the opposite side, when we allocate space for already closed
LWBs, when we precisely know how much space we need, we may just
allocate what we need instead of relying on writing less than
allocated, that does not work for RAIDZ.
Space for LWBs in open state (still being filled) is allocated

So, we put a flag on in-flight LWBs in zil_crash() when we move them

The vast majority of calls to zil_commit() follow VFS ops, and should
honour the failmode= setting - either wait for sync, or return error.
Some calls however are part of a larger syncing op, and shouldn't ever
block if something goes wrong.
To allow this, we introduce zil_commit_flags(), with a flag
ZIL_COMMIT_FAILMODE to indicate whether or not the pool failmode should
be honoured. zil_commit() is now a wrapper that always sets this flag,
but any caller wanting a different behaviour can request ZIL_COMMIT_NOW
instead to have the call return failure if the pool suspends, regardless
of the failmode= setting.

Closes#17398
If the ZIL runs into trouble, it calls txg_wait_synced(), which blocks
on suspend. We want it to not block on suspend, instead returning an
error. On the surface, this is simple: change all calls to
txg_wait_synced_flags(TXG_WAIT_SUSPEND), and then thread the error
return back to the zil_commit() caller.
Handling suspension means returning an error to all commit waiters. This
is relatively straightforward, as zil_commit_waiter_t already has
zcw_zio_error to hold the write IO error, which signals a fallback to
txg_wait_synced_flags(TXG_WAIT_SUSPEND), which will fail, and so the
waiter can now return an error from zil_commit().
However, commit waiters are normally signalled when their associated
write (LWB) completes. If the pool has suspended, those IOs may not
return for some time, or maybe not at all. We still want to signal those
waiters so they can return from zil_commit(). We have a list of those
in-flight LWBs on zl_lwb_list, so we can run through those, detach them
and signal them. The LWB itself is still in-flight, but no longer has
attached waiters, so when it returns there will be nothing to do.
(As an aside, ITXs can also supply completion callbacks, which are
called when they are destroyed. These are directly connected to LWBs
though, so are passed the error code and destroyed there too).
At this point, all ZIL waiters have been ejected, so we only have to
consider the internal state. We potentially still have ITXs that have
not been committed, LWBs still open, and LWBs in-flight. The on-disk ZIL
is in an unknown state; some writes may have been written but not
returned to us. We really can't rely on any of it; the best thing to do
is abandon it entirely and start over when the pool returns to service.
But, since we may have IO out that won't return until the pool resumes,
we need something for it to return to.
The simplest solution I could find, implemented here, is to "crash" the
ZIL: accept no new ITXs, make no further updates, and let it empty out
on its normal schedule, that is, as txgs complete and zil_sync() and
zil_clean() are called. We set a "restart txg" to three txgs in the
future (syncing + TXG_CONCURRENT_STATES), at which point all the
internal state will have been cleared out, and the ZIL can resume
operation (handled at the top of zil_clean()).
This commit adds zil_crash(), which handles all of the above:
- sets the restart txg
- capture and signal all waiters
- zero the header
zil_crash() is called when txg_wait_synced_flags(TXG_WAIT_SUSPEND)
returns because the pool suspended (ESHUTDOWN).
The rest of the commit is just threading the errors through, and related
housekeeping.

making ZFS to keep blocks logical birth times while rewriting

During regular block writes ZFS sets both logical and physical
birth times equal to the current TXG. During dedup and block
cloning logical birth time is still set to the current TXG, but
physical may be copied from the original block that was used.
This represents the fact that logically user data has changed,
but the physically it is the same old block.
But block rewrite introduces a new situation, when block is not
changed logically, but stored in a different place of the pool.
From ARC, scrub and some other perspectives this is a new block,
but for example for user applications or incremental replication
it is not. Somewhat similar thing happen during remap phase of
device removal, but in that case space blocks are still acounted
as allocated at their logical birth times.
This patch introduces a new "rewrite" flag in the block pointer
structure, allowing to differentiate physical rewrite (when the
block is actually reallocated at the physical birth time) from
the device reval case (when the logical birth time is used).
The new functionality is not used at this point, and the only
expected change is that error log is now kept in terms of physical
physical birth times, rather than logical, since if a block with
logged error was somehow rewritten, then the previous error does
not matter any more.
This change also introduces a new TRAVERSE_LOGICAL flag to the
traverse code, allowing zfs send, redact and diff to work in
context of logical birth times, ignoring physical-only rewrites.
It also changes nothing at this point due to lack of those writes,
but they will come in a following patch.

Closes#17581
FreeBSD commit 2ec2ba7e232d added the Solaris style syscall interface
for extended attributes. This patch wires this interface into the
FreeBSD ZFS port, since this style of extended attributes is supported
by OpenZFS internally when the "xattr" property is set to "dir".
Some specific changes:
LOOKUP_NAMED_ATTR is defined to indicate the need to set V_NAMEDATTR
for calls to zfs_zaccess().
V_NAMEDATTR indicates that the access checking does need to be done
for FreeBSD.
The access checking code for extended attributes was copy/pasted from
the Linux port into zfs_zaccess() in the FreeBSD port.
Most of the changes are in zfs_freebsd_lookup() and
zfs_freebsd_create().
The semantics of these functions should remain unchanged unless named
attributes are being manipulated.
All the code changes are enabled for __FreeBSD_version 1500040 and
newer.

Closes#17540
During original block cloning implementation a mistake was made,
making BRT ZAP entries an array of 8 1-byte entries instead of 1
entry of 8 bytes. This makes the pools non-endian-safe.
This commit introduces a new read-compatible pool feature
"com.truenas:block_cloning_endian", fixing the endianness issue
for new pools while maintaining compatibility with existing ones.
The feature is automatically activated when creating the first BRT
ZAP (ensuring we don't activate it on pools that already have BRT
entries in the old format). When active, BRT entries are stored
as single 8-byte values.

Closes#17572
Add support for the '-a | --all' option to perform trim,
scrub, and initialize operations on all pools.
Previously, specifying a pool name was mandatory for
these operations. With this enhancement, users can now
execute these operations across all pools at once,
without needing to manually iterate over each pool
from the command line.

Probably just an oversight in 4d044c4c1d. SPA_VDEVBITS is always 24,
regardless of whether or not the bp is for an encrypted block, and it
wouldn't make sense for it to be different anyway.

Seems like we haven't set it since the SPL was pulled into the main ZFS
tree. In removing the define, I've taken the 64-bit version (ie the one
that _hasn't_ been running since back then) because it looks like its
closer to the intended width by the way its used.
Since the macros ar eno longer needed as a selector, pull those too.
