From the kernel patch that this test examines ("xfs: detect agfl
count corruption and reset agfl"):
"The struct xfs_agfl v5 header was originally introduced with
unexpected padding that caused the AGFL to operate with one less
slot than intended. The header has since been packed, but the fix
left an incompatibility for users who upgrade from an old kernel
with the unpacked header to a newer kernel with the packed header
while the AGFL happens to wrap around the end. The newer kernel
recognizes one extra slot at the physical end of the AGFL that the
previous kernel did not. The new kernel will eventually attempt to
allocate a block from that slot, which contains invalid data, and
cause a crash.
"This condition can be detected by comparing the active range of the
AGFL to the count. While this detects a padding mismatch, it can
also trigger false positives for unrelated flcount corruption. Since
we cannot distinguish a size mismatch due to padding from unrelated
corruption, we can't trust the AGFL enough to simply repopulate the
empty slot.
"Instead, avoid unnecessarily complex detection logic and and use a
solution that can handle any form of flcount corruption that slips
through read verifiers: distrust the entire AGFL and reset it to an
empty state. Any valid blocks within the AGFL are intentionally
leaked. This requires xfs_repair to rectify (which was already
necessary based on the state the AGFL was found in). The reset
mitigates the side effect of the padding mismatch problem from a
filesystem crash to a free space accounting inconsistency."
This test exercises the reset code by mutating a fresh filesystem to
contain an agfl with various list configurations of correctly wrapped,
incorrectly wrapped, not wrapped, and actually corrupt free lists; then
checks the success of the reset operation by fragmenting the free space
btrees to exercise the agfl. Kernels without this reset fix will shut
down the filesystem with corruption errors.

Previously _scratch_mount didn't check the mount status and most
tests continue to run even if the mount failed (unless test checks
for the mount status explicitly). This would result in running tests
on the underlying filesystem (usually rootfs) and implicit test
failures, and such failures can be annoying and are usually hard to
debug.
Now _fail test by default if _scratch_mount failed and introduce
_try_scratch_mount for tests that need to check mount results
themselves.

Kernel commit f59cf5c29919 ("xfs: remove "no-allocation"
reservations for file creations") is known to cause earlier ENOSPC
conditions, and xfs/015 is affected in the way that no new file/dir
can be created in a newly created 16M XFS with both reflink and
rmapbt enabled, thus xfs/015 fails due to the missing test dirs.
So enlarge the initial fs size to 32M that we're able to create new
dir/file before growing the filesystem size.
Note that we doubled the fs initial size, we need to double the
required space too.

The XFS rmapbt extent swap mechanism performs an extent by extent
swap to ensure the rmapbt is rectified with the appropriate extent
owner information after the operation. This implementation suffers
from a corner case that requires extra reservation if the swap
operation results in bouncing one of the associated inodes between
extent and btree formats. When this corner case occurs, it results
in a transaction block reservation overrun and possible corruption
of the free space accounting.
This regression test provides coverage for this corner case. It
creates two files with a large enough extent count to require btree
format, regardless of inode size, and performs a sequence of extent
swaps between them with a decreasing extent count until all extents
are removed from the file(s). This ensures that one of the swaps
covers the btree <-> extent fork format boundary case.
This test reproduces fs corruption on rmapbt enabled filesystems
running on kernels without the associated extent swap fix.

test looks for problems when we have speculative cow reservations in

new owner. The second test checks that we remembered to dqattach
the inodes before performing reflink operations. The third is a

We're removing from XFS the ability to perform no-allocation file
creation. This was added years ago because some customer of SGI
demanded that we still be able to create (empty?) files with zero
free blocks remaining so long as there were free inodes and space in
existing directory blocks. This came at an unacceptable risk of
ENOSPC'ing midway through a transaction and shutting down the fs, so
we're removing it for the create case having changed our minds 20
years later.
However, some tests fail as a result, so fix them to be more
flexible about not failing when a dir/file creation fails due to
ENOSPC.

util-linux commit ea848180dd34 ("libmount: add

EUCLEAN and ESTALE again (and maybe other errno too):
- mount: <device> on <mountpoint> failed: Structure needs cleaning
+ mount: <mountpoint>: mount(2) system call failed: Structure needs cleaning.
and it causes xfs/005, overlay/037 to fail (and probably xfs/333 too,
but it's always _notrun for now).
And what's more, the mentioned tests would also fail when testing
with util-linux prior to v2.21, no one complained just because the
tests are usually _notrun on such old distributions that ship
util-linux < v2.21.
So let's filter out the changing parts and keep the error message
