When running zpool iostat in interval mode, it would not notice any new
pools created or imported, and would forget any destroyed or exported,
so would not notice if they came back. This leads to outputting "no
pools available" every interval until killed.
It looks like this was at least intended to work; the comment above
zpool_do_iostat() indicates that it is expected to "deal with pool
creation/destruction" and that pool_list_update() would detect new
pools. That call however was removed in 3e43edd2c5, though its unclear
if that broke this behaviour and it wasn't noticed, or if it never
worked, or if something later broke it. That said, the lack of
pool_list_update() is only part of the reason it doesn't work properly.
The fundamental problem is that the various things involved in
refreshing or updating the list of pools would aggressively ignore,
remove, skip or fail on pools that stop existing, or that already exist.
Mostly this meant that once a pool is removed from the list, it will
never be seen again. Restoring pool_list_update() to the
zpool_do_iostat() loop only partially fixes this - it would find "new"
pools again, but only in the "all pools" (no args) mode, and because its
iterator callback add_pool() would abort the iterator if it already has
a pool listed, it would only add pools if there weren't any already.
So, this commit reworks the structure somewhat. pool_list_update()
becomes pool_list_refresh(), and will ensure the state of all pools in
the list are updated. In the "all pools" mode, it will also add new
pools and remove pools that disappear, but when a fixed list of pools is
used, the list doesn't change, only the state of the pools within it.
The rest of the commit is adjusting things for this much simpler
structure. Regardless of the mode in use, pool_list_refresh() will
always do the right thing, so the driver code can just get on with the
display.
Now that pools can appear and disappear, I've made it so the header (if
enabled) is re-printed when the list changes, so that its easier to see
what's happening if the column widths change.
Since this is all rather complicated, I've included tests for the "all
pools" and "set of pools" modes.

This changes the basic search algorithm from a single search up and down
the tree to a full depth-first traversal to handle conditions where the
tree matches at a higher level but not a lower level.
Normally higher level blocks always point to matching blocks, but there
are cases where this does not happen:
1. Racing block pointer updates from dbuf_write_ready.
Before f664f1ee7f (#8946), both dbuf_write_ready and
dnode_next_offset held dn_struct_rwlock which protected against
pointer writes from concurrent syncs.
This no longer applies, so sync context can f.e. clear or fill all
L1->L0 BPs before the L2->L1 BP and higher BP's are updated.
dnode_free_range in particular can reach this case and skip over L1
blocks that need to be dirtied. Later, sync will panic in
free_children when trying to clear a non-dirty indirect block.
This case was found with ztest.
2. txg > 0, non-hole case. This is #11196.
Freeing blocks/dnodes breaks the assumption that a match at a higher
level implies a match at a lower level when filtering txg > 0.
Whenever some but not all L0 blocks are freed, the parent L1 block is
rewritten. Its updated L2->L1 BP reflects a newer birth txg.
Later when searching by txg, if the L1 block matches since the txg is
newer, it is possible that none of the remaining L1->L0 BPs match if
none have been updated.
The same behavior is possible with dnode search at L0.
This is reachable from dsl_destroy_head for synchronous freeing.
When this happens open context fails to free objects leaving sync
context stuck freeing potentially many objects.
This is also reachable from traverse_pool for extreme rewind where it
is theoretically possible that datasets not dirtied after txg are
skipped if the MOS has high enough indirection to trigger this case.
In both of these cases, without backtracking the search ends prematurely
as ESRCH result implies no more matches in the entire object.

Three cases were discovered where 'zpool add' would fail to
warn when adding vdevs to a pool with a mismatched replication
level. These are:
1. When a pool contains mixed file and disk vdevs.
2. When a pool contains an active dRAID distributed spare
3. When a pool contains an active hot spare
The lack of warnings are caused by get_replication() assessing
the current pool configuration an inconsistent and disabling
the mismatched replication check for the new pool configuration
after 'zpool add'. This change updates get_replication() to
be slightly more tolerant in the non-fatal case.

Traditionally, unused dentries would be cached in the dentry cache until

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.

Instead, take the write lock before finishing up and decoupling the disk

Historically, ZED has blindly spawned off zedlets in parallel and never
worried about their completion order. This means that you can
potentially have zedlets for event number 2 starting before zedlets for
event number 1 had finished. Most of the time this is fine, and it
actually helps a lot when the system is getting spammed with hundreds
of events.
However, there are times when you want your zedlets to be executed
in sequence with the event ID. That is where synchronous zedlets
come in.
ZED will wait for all previously spawned zedlets to finish before
running a synchronous zedlet. Synchronous zedlets are guaranteed to be
the only zedlet running. No other zedlets may run in parallel with a
synchronous zedlet. Users should be careful to only use synchronous
zedlets when needed, since they decrease parallelism.
To make a zedlet synchronous, simply add a "-sync-" immediately
following the event name in the zedlet's file name:
EVENT_NAME-sync-ZEDLETNAME.sh
For example, if you wanted a synchronous statechange script:

While it would be nice to be able to scrub a pool imported read-only
this will currently trip an ASSERT. Before we can support this there
are some designs challenges which need to be thought through first.
For starters, a read-only import skips reading certain information
from disk which it knows won't be needed, such as the space maps.
Furthermore, the scrub process expects to be checkpoint it's progress,
update the on disk error log, and issue repair IO. None of which
would be possible when the pool is imported read-only.
Each of these wrinkles can certainly be handled, but that will take
some signifcant work. In the meanwhile we disable the 'zpool scrub'

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

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.
