If preemption is disabled, all metadata buffers needed to perform the
scrub are already in memory, and there are a lot of records to check,
it's possible that the scrub thread will run for an extended period of
time without sleeping for IO or any other reason. Then the watchdog

above.
To fix this problem, call cond_resched() from the scrub thread so that
we back out to the scheduler whenever necessary.

Scrubbing directories, quotas, and fs counters all involve iterating
some collection of metadata items. The per-item scrub functions for
these three are missing some of the components they need to be able to
check for a fatal signal and terminate early.
Per-item scrub functions need to call xchk_should_terminate to look for
fatal signals, and they need to check the scrub context's corruption
flag because there's no point in continuing a scan once we've decided
the data structure is bad. Add both of these where missing.

The inode block mapping scrub function does more work for btree format
extent maps than is absolutely necessary -- first it will walk the bmbt
and check all the entries, and then it will load the incore tree and
check every entry in that tree, possibly for a second time.
Simplify the code and decrease check runtime by separating the two
responsibilities. The bmbt walk will make sure the incore extent
mappings are loaded, check the shape of the bmap btree (via xchk_btree)
and check that every bmbt record has a corresponding incore extent map;
and the incore extent map walk takes all the responsibility for checking
the mapping records and cross referencing them with other AG metadata.
This enables us to clean up some messy parameter handling and reduce
redundant code. Rename a few functions to make the split of
responsibilities clearer.

if (ds->state->altpath.blk[level].bp)

xfs_trans_brelse(..., ds->state->altpath.blk[level].bp);
struct xfs_buf_log_item *bip = bp->b_log_item;

Thus, possible null-pointer dereferences may occur.

being used.

The xattr scrubber functions use the temporary memory buffer either for
storing bitmaps or for testing if attribute value extraction works. The
bitmap code always zeroes what it needs and the value extraction sets
the buffer contents, so it's not necessary to waste CPU time zeroing on
allocation.
Note that while we never read the contents that the attr value
extraction function sets, we do need to call it to check the remote
attribute header and CRCs to check for corruption.
A flame graph analysis showed that we were spending 7% of a xfs_scrub
run (the whole program, not just the attr scrubber itself) allocating
and zeroing 64k segments needlessly.

In examining a flame graph of time spent running xfs_scrub on various
filesystems, I noticed that we spent nearly 7% of the total runtime on
allocating a zeroed 65k buffer for every SCRUB_TYPE_XATTR invocation.
We do this even if none of the attribute values were anywhere near 64k
in size, even if there were no attribute blocks to check space on, and
even if it just turns out there are no attributes at all.
Therefore, rearrange the xattr buffer setup code to support reallocating
with a bigger buffer and redistribute the callers of that function so
that we only allocate memory just prior to needing it, and only allocate
as much as we need. If we can't get memory with the ILOCK held we'll
bail out with EDEADLOCK which will allocate the maximum memory.
