968cfc3df2 zdb: add --class=(normal|special|...) to filter blocks by alloc class
When counting blocks to generate block size histograms (`-bb`), accept a
`--class=` argument (as a comma-separated list of either "normal",
"special", "dedup" or "other") to only consider blocks that belong to
these metaslab classes.

627b530059 zdb: add --bin=(lsize|psize|asize) arg to control histogram binning
When counting blocks to generate block size histograms (`-bb`), accept a
`--bin=` argument to force placing blocks into all three bins based on
*this* size.

E.g. with `--bin=lsize`, a block with lsize=512K, psize=128K, asize=256K
will be placed into the "512K" bin in all three output columns. This
way, by looking at the "512K" row the user will be able to determine
how well was ZFS able to compress blocks of this logical size.

Conversely, with `--bin=psize`, by looking at the "128K" row the user
will be able to determine how much overhead was incurred for storage
of blocks of this physical size.

3e7e19e028 pool_iter_refresh: don't refresh pools twice
In "all pools" mode, pool_iter_refresh() will call zpool_iter(), which
will call zpool_refresh_stats() before calling add_pool(). If we already
have the pool, this is a different handle, so we just release it and
return. Back in pool_iter_refresh(), we then call zpool_stats_refresh()
again for our handle on the same pool.

All together, this means we're doing two ZFS_IOC_POOL_STATS calls into
the kernel for every pool in the system. This isn't wrong, but it does
double the pressure on global locks.

Instead, we add a new function zpool_refresh_stats_from_handle() that
simply copies the pool config and state from one handle to another, and
use it to update our handle before we release it in add_pool(), so we
only have one call per pool per interval.

4c84b77bc4 pool_iter_refresh: don't flag existing pools as refreshed
zpool_iter() passes the callback a new instance of zpool_handle_t each
time, so the existing handle in the pool_list AVL never actually gets a
refresh. Internally, that means its zpool_config is never updated, and
the old config is never moved to zpool_old_config. As a result,
print_iostat() never sees any updated config, and so repeats the first
line forever.

This is the simplest workaround: just don't mark existing pools as
refreshed. pool_list_refresh() will see this and refresh them.
The downside is a second call to ZFS_IOC_POOL_STATS for existing pools,
because zpool_iter() just called it for the handle we threw away.

37d8d4619f zpool iostat: update pool counter when skipping boot row
When skipping the boot row (with -y), the early loop meant we weren't
updating the "last_npools" count. That means the count never advanced
past zero, so cb_iteration was always reset to 0, leading to it being
"stuck" on the boot line, printing the header and nothing else forever.

Updating the pool counter on every loop sorts that out: it advances,
cb_iteration moves properly, and normal rows are printed.

073b34b3ee Fix display of default xattr to show 'sa'
When the default value of the xattr property was changed from 'dir' to
'sa', the code that displays the property's value was not affected. The
problem with this state of affairs is that 1) user tooling that
specifically looked for 'sa' before will be confused now that the code
displays 'on' instead. And 2) users may be confused when manually
running the commands about which specific type of xattr is in use unless
they are up to date on the latest zfs changes.

The fix here is to show the actual type always, rather than 'on' if we
happen to be using the default. This turns out to be easy to do, by
simply reordering the list of xattr values in the properties code. When
the property is displayed, we iterate down the table until we find a row
with a matching value, and use that row's name as the
display. Reordering the row fixes the display without affecting any
other code.

35ec4b14ab zpool iostat: refresh pool list every interval
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.

460858dfd6 dnode_next_offset: backtrack if lower level does not match
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.

d33d0cac5a Fix 'zpool add' safety check corner cases
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.

The zpool_add_010_pos.ksh test case was split in to separate
tests: zpool_add_warn_create.ksh, pool_add_warn_degraded.ksh,
and zpool_add_warn_removal.  These test were extended to
include coverage for dRAID pools and the three scenarios
described above.

We hit an assertion trying to run `zdb -bvy` on a large pool.  But
it seems the code does not really need size there, since we only

just make btree return position just before the first entry.  I
suspect the previous code could actually miss the first entry
due to this if its size was smaller.

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.

42b9995f88 linux/super: add tunable to request immediate reclaim of unused inodes
Traditionally, unused inodes would be held on the superblock inode cache
until the associated on-disk file is removed or the kernel requests
reclaim.  On filesystems with millions of rarely-used files, this can be
a lot of unusable memory.

Here we implement the superblock drop_inode method, and add a
zfs_delete_inode tunable to control its behaviour. By default it
continues the traditional behaviour, but when the tunable is enabled, we
signal that the inode should be deleted immediately when the last
reference is dropped, rather than cached. This releases the associated
data to the dbuf cache and ARC, allowing them to be reclaimed normally.

5f7253ca11 Refactor zhack label repair and fix -c regression on nonzero TXG
This commit fixes a likely regression introduced by 64db435 where the
checksum repair functionality (`-c` or default behavior) will perform
checks and access data associated with the newer undetach (`-u`)
functionality, resulting in a failure when an uberblock's TXG is not 0
as required by `-u` but not `-c`

Additionally, code is refactored for better separation of tasks.

8b548776ff zfsprops(7): attempt to clarify the keylocation description
The current description is somewhat difficult to parse through, and in
some cases is a little unclear as to the behavior.

Split it into a paragraphs based on the three distinct behaviors you
may get: prompt, file URL, HTTP(S) URL.  The descriptions of the file
and HTTP(s) behavior seems fine, but prompt is a little vague- expand
on it and make it clear that the behavior is actively based on whether
the inquisitor of key-data is provided with a tty for stdin or not.

Also clarify *why* one shouldn't "place keys which should be kept secret
on the command line" and note that you *have* to supply the key via
stdin if it's a raw key, just to be sure.

when the "data" argument isn't specified.  This ensures the default
behavior is to perform a more realistic fill of incompressible blocks.

Additionally, update a few test cases to specify a random fill.

da33cfd436 vdev_disk_close: take disk write lock before destroying it
Many IO operations are submitted to the kernel async, and so the zio can
complete and followup actions before the submission call returns. If one
of the followup actions closes the disk (eg during pool create/import),
the initiator may be left holding a lock on the disk at destruction.

Instead, take the write lock before finishing up and decoupling the disk
state from the vdev proper. The caller will hold until all IO is
submitted and locks released.
