XFS allocates extra indirect blocks for delayed allocation extents at
write time. When delalloc extents are split, the existing indirect block
reservation was historically divided up evenly among the new extents
even though the overall requirement for two extents could exceed the
requirement for the original. Repeated delalloc extent splits ultimately
leads to extents with 0 indirect blocks and in turn leads to assert
failures in XFS.
Add a test to stress indirect block reservation for delayed allocation
extents. The test converts a single delalloc extent to many and operates
on the remaining extents to detect or trigger potential problems.

XFS had a data corruption problem where writeback of pages to unwritten
extents would fail to run unwritten extent conversion at I/O completion.
This causes subsequent reads of written, but unconverted regions to
return zeroes. This occurs on sub-page block size filesystems when
writeback contends for the inode lock (e.g., with a file writer).
Add a test that creates the conditions to reproduce the data corruption
and detect it by looking for unwritten extents after all said extents
have been overwritten.

then failed of the fcollapse returned an EBUSY error.

I'm getting enospc errors on a 4GB test device after a while of
running. Part of the issue is that many tests can't or don't clean
up previous failed runs when they start or if the run to success.
Hence while we want to slowly age the test filesystem, we don't
really want that aging to unintentionally run the filesystem out of
space. To that end:
$ sudo du -s /mnt/test/* | sort -nr |head -10
1929160 /mnt/test/fsfile
512000 /mnt/test/247.8133
512000 /mnt/test/247.4713
512000 /mnt/test/247.4488

26208 /mnt/test/populate_root
26208 /mnt/test/mnt
23216 /mnt/test/fsstress.4491.1
We can see that there are a few tests that using most of the space.
These are often left behind due to kernel failures during tests or
reboots while tests are in progress, so make sure that they at least
clean up such mess the next time they run.
Test generic/247, xfs/020 (fsfile) and generic/074 (fstest.$$.n)
are the worst offenders, so just target these to being with.

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.
