Workaround for #12762Closes#13256
On machines using systemd, trim timers can be enabled on a per-pool
basis. Weekly and monthly timer units are provided. Timers can be
enabled as follows:
systemctl enable zfs-trim-weekly@rpool.timer --now
systemctl enable zfs-trim-monthly@datapool.timer --now
Each timer will pull in zfs-trim@${poolname}.service, which is not
schedule-specific.
The manpage zpool-trim has been updated accordingly.

There's one substantial difference: ZFS_MODULE_TIMEOUT=-1

Add support for a -exclude/-X option to `zfs send` to allow dataset
hierarchies to be excluded.
Snapshots can be excluded using a channel program; however,
this can result in failures with 'zfs send -R'; this option allows
them to be excluded. Fortunately, this required a change only to
cmd/zfs/zfs_main.c, using the already-existing callback argument
to zfs_send() that is currently unused.

wall-real 0.014518s/0.003467s=4.18668x
But this is a big win on machines with a lot of datasets and expensive

FreeBSD historically has not cared about the xattr property; it was
always treated as xattr=on. With xattr=on, xattrs are stored as files
in a hidden xattr directory. With xattr=sa, xattrs are stored as
system attributes and get cached in nvlists during xattr operations.
This makes SA xattrs simpler and more efficient to manipulate. FreeBSD
needs to implement the SA xattr operations for feature parity with
Linux and to ensure that SA xattrs are accessible when migrated or
replicated from Linux.
Following the example set by Linux, refactor our existing extattr vnops
to split off the parts handling dir style xattrs, and add the
corresponding SA handling parts.
