This test tries to directly corrupt the CRC field of the primary
superblock by using xfs_io pwrite, but never syncs it to disk,
so it's quite likely that the mount will not see the bad data.

A buffer use after free race was discovered in the XFS log recovery
codepath if I/O failures occur during recovery. The I/O submission path
can abort the mount and release the only reference held on some buffers
before I/O completion processing (e.g., async workqueue processing)
might have completed. Badness ensues if the I/O completion path
subsequently attempts to access said buffers.
The test manufactures the race by forcing all writes to fail (via
dm-flakey) after a fixed period of time. A delay is inserted into the
mount codepath to synchronize write failures with log recovery.
Credit for discovery of the race and definition of the reproducible test
case goes to Alex Lyakas.

_require_xfs_sysfs() currently assumes that all sysfs attributes reside
under a device-specific subdirectory in the XFS sysfs hierarchy. It is
hardcoded to use the TEST_DEV mount and expect the relative attribute
path as a parameter.
Not all sysfs attributes are associated with specific devices or mount
points, however. Remove the hardcoded device name part of the attribute
path from _require_xfs_sysfs() and let the caller construct the relative
path based on the sysfs XFS root directory.

Some tests deliberately corrupt scratch devices and so will fail
the post-test check. Add a "_require_scratch_nocheck" helper
function for such tests to avoid false test failure detection.
Also, ensure that _notrun cleans up the trigger for the post-test
checks. Otherwise the next test to run may try to validate the
scratch/test devices even though they are not used by the test.
Further, _check_xfs_filesystem() causes check to exit if it finds a
corruption. This is extremely annoying as it terminates the entire
test run rather than just reporting that the test fails. Hence add
an "iam != check" test before exiting so that calls from tests will
cause the test to fail, but calls from check won't cause the harness
to exit.
There are still some tests that fail the scratch check, these are
not obvious test failures and so need further investigation to
determine the cause of the failures.

test xfs/291 creates an xfs_metadump image and runs repair on it.
Technically, this is supposed to require "-f" to specify that
the target of the repair is a file; this allows buffered IO fallback
in the case where the image sector size is smaller than the device
sector size. And in fact if we create the image on a hard 4k device,
the test will fail when repair is unable to operate on the image.
So add that -f!

Changes in the XFS logging code have lead to small leaks in the log
grant heads that consume log space slowly over time. Such problems have
gone undetected for an unnecessarily long time due to code complexity
and potential for very subtle problems. Losing only a few bytes per
logged item on a reasonably large enough fs (10s of GB) means only the
most continuously stressful workloads will cause a severe enough failure
(deadlock due to log reservation exhaustion) quickly enough to indicate
something is seriously wrong.
Recent changes in XFS export the state of the various log heads through
sysfs to aid in userspace/runtime analysis of the log. This test runs a
workload against an XFS filesystem, quiesces the fs and verifies that
the log reserve and write grant heads have not leaked any space with
respect to the current head of the physical log.

XFS can allocate significant amounts of space to files via speculative
preallocation. Such preallocation may not be reclaimed automatically on
file close() if a file is repeatedly opened and extended. For smaller
filesystems with relatively large and slow growing files, this
preallocation can linger for some time, including contributing to out of
space conditions.
Create a situation where an fs is near out of space while several files
still have lingering, significant preallocations. Verify that new
writers reclaim the preallocated space rather than return ENOSPC. Repeat
a similar test for quota limits and EDQUOT.

It has been reported that test xfs/013 probably uses more space than
necessary, exhausting space if run against a several GB sized ramdisk.
xfs/013 primarily creates, links and removes inodes. Most of the space
consumption occurs via the background fsstress workload.
Remove the fsstress -w option that suppresses non-write operations. This
slightly reduces the storage footprint while still providing a
