Rob Norris 72e6144851 config: remove no-op tests
All these checks abort configure if they fail. They're looking for
things that have existed forever, and so never fail. While they do have
some tiny value in detecting if these ever change, we'll also get that
from the build breaking. Removing them is a bunch of work we don't have
to do on every run.

config: don't force shared linkage on FreeBSD
-shared was hardcoded, so when building with --disable-shared it amounts
to trying to do shared linkage against static libs, which naturally
fails.

Make txg_wait_synced conditional in zfsvfs_teardown, for FreeBSD
This applies the same change in #9115 to FreeBSD.  This was actually the
old behavior in FreeBSD 12; it only regressed when FreeBSD support was
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  slightly outdated OpenZFS code.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
with a large pool that has 1000 datasets and is resilvering an HDD.

Linux: Make zfs_prune() fair on NUMA systems
Previous code evicted nr_to_scan items from each NUMA node.  This
not only multiplied the eviction by the number of nodes, but could
exhaust the smaller ones, evicting inodes used by acive workload
and requiring their immediate recreation.  This patch spreads the
requested eviction between all NUMA nodes proportionally to their
evictable counts, which should be closer to expected LRU logic.
See kernel's super_cache_scan() as a similar logic example.

Soften pruning threshold on not evictable metadata
Previous code pruned 10% of dnodes once 3/4 of metadata appeared
unevictable.  On workloads with many millions of dnodes and little
other metadata it creates significant load spikes for many seconds
straight.  This change instead gradually increases pruning as
unevictable metadata grow above the 3/4, which may allow it to
stabilize at some level.

Improve zfs_blkptr_verify()
- Skip config lock enter/exit for embedded blocks.  They have no

 - Skip CHECKSUM check and properly check PSIZE for embedded blocks.
 - Add static branch predictions for unlikely conditions.
 - Do not verify DVAs for blocks already in ARC.  ARC hit already
"verified" the first (often the only) DVA, and it does not worth to
enter/exit config lock for nothing.

Some profiles show me up to 3% of CPU saving from this change.

Mateusz Piotrowski 24e6585e76 libzfs.h: Set ZFS_MAXPROPLEN and ZPOOL_MAXPROPLEN to ZAP_MAXVALUELEN
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.

Mark Johnston dea8fabf73 FreeBSD: Fix RLIMIT_FSIZE handling for block cloning
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.

ZTS: small fix for SEEK_DATA/SEEK_HOLE tests (#16413)
Some libc's like uClibc lag the proper definition of SEEK_DATA

these definitons, let's define them by hand:

```
#ifndef SEEK_DATA
#define SEEK_DATA 3
#endif
#ifndef SEEK_HOLE
#define SEEK_HOLE 4
#endif
```

There should be no failures, because:
- FreeBSD has support for SEEK_DATA/SEEK_HOLE since FreeBSD 8
- Linux has it since Linux 3.1
- the libc will submit the parameters unchanged to the kernel

Tony Hutter 02a9f7fed7 JSON: Fix class values for mirrored special vdevs
This fixes things so mirrored special vdevs report themselves as
"class=special" rather than "class=normal".

This happens due to the way the vdev nvlists are constructed:

mirrored special devices - The 'mirror' vdev has allocation bias as
"special" and it's leaf vdevs are "normal"

single or RAID0 special devices - Leaf vdevs have allocation bias as
"special".

This commit adds in code to check if a leaf's parent is a "special"
vdev to see if it should also report "special".

Last commit should fix the underlying problem, so these should be
passing reliably again.

Rob Norris 670147be53 zvol: ensure device minors are properly cleaned up
Currently, if a minor is in use when we try to remove it, we'll skip it
and never come back to it again. Since the zvol state is hung off the
minor in the kernel, this can get us into weird situations if something
tries to use it after the removal fails. It's even worse at pool export,
as there's now a vestigial zvol state with no pool under it. It's
weirder again if the pool is subsequently reimported, as the zvol code
(reasonably) assumes the zvol state has been properly setup, when it's
actually left over from the previous import of the pool.

This commit attempts to tackle that by setting a flag on the zvol if its
minor can't be removed, and then checking that flag when a request is
made and rejecting it, thus stopping new work coming in.

The flag also causes a condvar to be signaled when the last client
finishes. For the case where a single minor is being removed (eg
changing volmode), it will wait for this signal before proceeding.
Meanwhile, when removing all minors, a background task is created for
each minor that couldn't be removed on the spot, and those tasks then
wake and clean up.

Since any new tasks are queued on to the pool's spa_zvol_taskq,
spa_export_common() will continue to wait at export until all minors are
removed.
