71fa062196 xfs: centralize error tag definitions
Right now 5 places in the kernel and one in xfsprogs need to be updated
for each new error tag.  Add a bit of macro magic so that only the
error tag definition and a single table, which reside next to each
other, need to be updated.

Don't pass expr to XFS_TEST_ERROR.  Most calls pass a constant false,

8e2cdd8e18 xfs: adjust the hint based zone allocation policy
As we really can't make any general assumptions about files that don't
have any life time hint set or are set to "NONE", adjust the allocation
policy to avoid co-locating data from those files with files with a set

0301dae732 xfs: refactor hint based zone allocation
Replace the co-location code with a matrix that makes it more clear
on how the decisions are made.

The matrix contains scores for zone/file hint combinations. A "GOOD"
score for an open zone will result in immediate co-location while "OK"
combinations will only be picked if we cannot open a new zone.

e747883c7d xfs: fix log CRC mismatches between i386 and other architectures
When mounting file systems with a log that was dirtied on i386 on
other architectures or vice versa, log recovery is unhappy:

[   11.068052] XFS (vdb): Torn write (CRC failure) detected at log block 0x2. Truncating head block from 0xc.

This is because the CRCs generated by i386 and other architectures
always diff.  The reason for that is that sizeof(struct xlog_rec_header)
returns different values for i386 vs the rest (324 vs 328), because the
struct is not sizeof(uint64_t) aligned, and i386 has odd struct size
alignment rules.

This issue goes back to commit 13cdc853c519 ("Add log versioning, and new
super block field for the log stripe") in the xfs-import tree, which
adds log v2 support and the h_size field that causes the unaligned size.
At that time it only mattered for the crude debug only log header
checksum, but with commit 0e446be448 ("xfs: add CRC checks to the log")
it became a real issue for v5 file system, because now there is a proper
CRC, and regular builds actually expect it match.

Fix this by allowing checksums with and without the padding.

482c57805c xfs: improve online repair reap calculations [6.18 v2 1/2]
A few months ago, the multi-fsblock untorn writes patchset added a bunch
 of log intent item helper functions to estimate the number of intent
 items that could be added to a particular transaction.  Those helpers
 enabled us to compute a safe upper bound on the number of blocks that
 could be written in an untorn fashion with filesystem-provided out of
 place writes.
 
 Currently, the online fsck code employs static limits on the number of
 intent items that it's willing to accrue to a single transaction when
 it's trying to reap what it thinks are the old blocks from a corrupt
 structure.  There have been no problems reported with this approach
 after years of testing, but static limits are scary and gross because
 overestimating the intent item limit could result in transaction
 overflows and dead filesystems; and underestimating causes unnecessary
 overhead.
 
 This series uses the new log intent item size helpers to estimate the
 limits dynamically based on worst-case per-block repair work vs. the
 size of the scrub transaction.  After several months of testing this,
 there don't seem to be any problems here either.
 
 v2: rearrange patches, add review tags
 
 This has been running on the djcloud for months with no problems.  Enjoy!

d5b157e088 xfs: remove static reap limits from repair.h
Delete XREAP_MAX_BINVAL and XREAP_MAX_DEFER_CHAIN because the reap code
now calculates those limits dynamically, so they're no longer needed.

Move the third limit (XREP_MAX_ITRUNCATE_EFIS) to the one file that uses
it.  Note that the btree rebuilding code should reserve exactly the
number of blocks needed to rebuild a btree, so it is rare that the newbt
code will need to add any EFIs to the commit transaction.  That's why
that static limit remains.

e4c7eece76 xfs: compute file mapping reap limits dynamically
Reaping file fork mappings is a little different -- log recovery can
free the blocks for us, so we only try to process a single mapping at a

82e374405e xfs: prepare reaping code for dynamic limits
The online repair block reaping code employs static limits to decide if
it's time to roll the transaction or finish the deferred item chains to
avoid overflowing the scrub transaction's reservation.  However, the
use of static limits aren't great -- btree blocks are assumed to be
scattered around the AG and the buffers need to be invalidated, whereas
COW staging extents are usually contiguous and do not have buffers.  We
would like to configure the limits dynamically.

To get ready for this, reorganize struct xreap_state to store dynamic
limits, and add helpers to hide some of the details of how the limits
are enforced.  Also rename the "xreap roll" functions to include the
word "binval" because they only exist to decide when we should roll the
transaction to deal with buffer invalidations.

No functional changes intended here.

cd32a0c0dc xfs: use deferred intent items for reaping crosslinked blocks
When we're removing rmap records for crosslinked blocks, use deferred

structure's blocks as we can in the same transaction as the commit.
