The Linux kernel MODULE_LICENSE macro only recognizes a handful of
license strings and "MIT" is not one of the them.  Update the macro
to use "Dual MIT/GPL" which is recognized and what the kernel expects
MIT licensed modules to use.

Ryan Moeller 0dc6fb730f FreeBSD: Skip RAW kstat sysctls by default
These kstats are often expensive to compute so we want to avoid them
unless specifically requested.

The following kstats are affected by this change:

kstat.zfs.${pool}.multihost
kstat.zfs.${pool}.misc.state
kstat.zfs.${pool}.txgs
kstat.zfs.misc.fletcher_4_bench
kstat.zfs.misc.vdev_raidz_bench
kstat.zfs.misc.dbufs
kstat.zfs.misc.dbgmsg

In FreeBSD 13, sysctl(8) has been updated to still list the
names/description/type of skipped sysctls so they are still
discoverable.

Use proper names (i.e. zfs-allow and zpool-add) in NAME subsections
of zfs/zpool subcommands instead of current "pretty-printed" ones as
makewhatis utilities (or some implementations of it, namely the one
from mandoc suite used in FreeBSD) look not only at the document title
but also in NAME subsection, adding zfs(8)/zpool(8) to search results
which is not correct. (Common sense and other utilities splitting
subcommands in multiple man pages, e.g. git, do the same.)

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.

In C, const indicates to the reader that mutation will not occur.
It can also serve as a hint about ownership.

Add const in a few places where it makes sense.

John Poduska a09e3a8594 Mismatched nvlist names in zfs_keys_send_space
This causes "zfs send -vt ..." to fail with:

    cannot resume send: Unknown error 1030

It turns out that some of the name/value pairs in the verification
list for zfs_ioc_send_space(), zfs_keys_send_space, had the wrong
name, so the ioctl got kicked out in zfs_check_input_nvpairs().
Update the names accordingly.

Brian Behlendorf fc5966589b Fix buggy procfs_list_seq_next warning
The kernel seq_read() helper function expects ->next() to update
the passed position even there are no more entries.  Failure to
do so results in the following warning being logged.

    seq_file: buggy .next function procfs_list_seq_next [spl]
    did not update position index

Functionally there is no issue with the way procfs_list_seq_next()
is implemented and the warning is harmless.  However, we want to
silence this some what scary incorrect warning.  This commit
updates the Linux procfs code to advance the position even for
the last entry.

Matthew Macy 775afc4dcd Eliminate gratuitous bzeroing in dbuf_stats_hash_table_data
`dbuf_stats_hash_table_data` can take much longer than it needs to
by repeatedly bzeroing its buffer when in fact the buffer only needs
to be NULL terminated.

Sebastian Gottschall 7ce9da0bea do a cyclic seek for unused memory objects in pool
In non regular use cases allocated memory might stay persistent in memory
pool. This small patch checks every minute if there are old objects which
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
someone discovered this issue while doing tests. personally i know this
behavior and I'm aware of it. Its no big issue. just a enhancement

Ryan Moeller e58dee8cae Drop references when skipping dmu_send due to EXDEV
When an invalid incremental send is requested where the "to" ds is
before the "from" ds, make sure to drop the reference to the pool
and the dataset before returning the error.

Add an assert on FreeBSD to make sure we don't hold any locks after
returning from an ioctl.

Add some test coverage.
