Closes#15892
This is the supporting infrastructure for the upcoming dedup features.
Traditionally, dedup objects live directly in the MOS root. While their
details vary (checksum, type and class), they are all the same "kind" of
thing - a store of dedup entries.
The new features are more varied than that, and are better thought of as
a set of related stores for the overall state of a dedup table.
This adds a new feature flag, SPA_FEATURE_FAST_DEDUP. Enabling this will
cause new DDTs to be created as a ZAP in the MOS root, named
DDT-<checksum>. The is used as the root object for the normal type/class
store objects, but will also be a place for any storage required by new
features.
This commit adds two new fields to ddt_t, for version and flags. These
are intended to describe the structure and features of the overall dedup
table, and are stored as-is in the DDT root. In this commit, flags are
always zero, but the intent is that they can be used to hang optional
logic or state onto for new dedup features. Version is always 1.
For a "legacy" dedup table, where no DDT root directory exists, the
version will be 0.
ddt_configure() is expected to determine the version and flags features
currently in operation based on whether or not the fast_dedup feature is
enabled, and from what's available on disk. In this way, its possible to
support both old and new tables.
This also provides a migration path. A legacy setup can be upgraded to
FDT by creating the DDT root ZAP, moving the existing objects into it,
and setting version and flags appropriately. There's no support for that
here, but it would be straightforward to add later and allows the
possibility that newer features could be applied to existing dedup
tables.

Closes#15892
zvol queue limits initialization depends on `zv_volblocksize`, but it is
initialized later, leading to several limits being initialized with
incorrect values, including `max_discard_*` limits. This also causes
`blkdiscard` command to consistently fail, as `blk_ioctl_discard` reads
`bdev_max_discard_sectors()` limits as 0, leading to failure. The fix is
straightforward: initialize `zv->zv_volblocksize` early, before setting
the queue limits. This PR should fix `zvol/zvol_misc/zvol_misc_trim`
failure on recent PRs, as the test case issues `blkdiscard` for a zvol.
Additionally, `zvol_misc_trim` was recently enabled in `6c7d41a`,
which is why the issue wasn't identified earlier.

Closes#16454
If a zvol is renamed, and it has one or more snapshots, and
snapdev=visible is true for the zvol, then the rename causes a kernel
null pointer dereference error. This has the effect (on Linux, anyway)
of killing the z_zvol taskq kthread, with locks still held; which in
turn causes a variety of zvol-related operations afterward to hang
indefinitely (such as udev workers, among other things).
The problem occurs because of an oversight in #15486
(e36ff84c33). As documented in
dataset_kstats_create, some datasets may not actually have kstats
allocated for them; and at least at the present time, this is true for
snapshots. In practical terms, this means that for snapshots,
dk->dk_kstats will be NULL. The dataset_kstats_rename function
introduced in the patch above does not first check whether dk->dk_kstats
is NULL before proceeding, unlike e.g. the nearby
dataset_kstats_update_* functions.
In the very particular circumstance in which a zvol is renamed, AND that
zvol has one or more snapshots, AND that zvol also has snapdev=visible,
zvol_rename_minors_impl will loop over not just the zvol dataset itself,
but each of the zvol's snapshots as well, so that their device nodes
will be renamed as well. This results in dataset_kstats_create being
called for snapshots, where, as we've established, dk->dk_kstats is
NULL.
Fix this by simply adding a NULL check before doing anything in
dataset_kstats_rename.
This still allows the dataset_name kstat value for the zvol to be
updated (as was the intent of the original patch), and merely blocks
attempts by the code to act upon the zvol's non-kstat-having snapshots.
If at some future time, kstats are added for snapshots, then things
should work as intended in that case as well.

added to OpenZFS. As far as I can tell, the timeline went like this:
* Illumos's zfsvfs_teardown used an unconditional txg_wait_synced
* Illumos added the dirty data check [^4]
* FreeBSD merged in Illumos's conditional check [^3]
* OpenZFS forked from Illumos
* OpenZFS removed the dirty data check in #7795 [^5]
* @mattmacy forked the OpenZFS repo and began to add FreeBSD support
* OpenZFS PR #9115[^1] recreated the same dirty data check that Illumos
used, in slightly different form. At this point the OpenZFS repo did
not yet have multi-OS support.
* Matt Macy merged in FreeBSD support in #8987[^2] , but it was based on
slightly outdated OpenZFS code.
In my local testing, this vastly improves the reboot speed of a server

So far, the values of ZFS_MAXPROPLEN and ZPOOL_MAXPROPLEN were equal to
MAXPATHLEN, which is 1024 on FreeBSD and 4096 on Linux. This wasn't
ideal. Some of the surprising outcomes of this implementation are:
1. When creating a pool user property with zpool-set(8), libzfs makes
sure that the length of the property's value is less than
ZFS_MAXPROPLEN. However, the ZFS kernel module does not do that.
Instead, it checks the length against ZAP_MAXVALUELEN. As a result,
it is possible to create a property the length of which is going to
be larger than zpool(8) is ready to read.
2. A pool user property created on Linux is too big to be read on
FreeBSD.
This change sets both ZFS_MAXPROPLEN and ZPOOL_MAXPROPLEN to
ZAP_MAXVALUELEN, which is 8192 at the moment.

ZFS implements copy_file_range(2) using block cloning when possible.
This implementation must respect the RLIMIT_FSIZE limit.
zfs_clone_range() already checks the limit, so it is safe to remove this
check in zfs_freebsd_copy_file_range(). Moreover, the removed check
produces false positives: the length passed to copy_file_range(2) may be
larger than the input file size; as the man page notes, "for best
performance, call copy_file_range() with the largest len value
possible." In particular, some existing code passes SSIZE_MAX there.
The check in zfs_clone_range() clamps the length to the input file's
size before checking, but the removed check uses the caller supplied
length, so something like
$ echo a > /tmp/foo
$ limits -f 1024 cat /tmp/foo > /tmp/bar
fails because FreeBSD's cat(1) uses copy_file_range(2) in the manner
described above.
