Test that if we write into an unwritten extent of a file when there
is no more space left to allocate in the filesystem and then
snapshot the file's subvolume, after a clean shutdown the data was
not lost.
This test is motivated by a bug found by Robbie Ko for which there
is a fix whose patch title is:
"Btrfs: fix unexpected failure of nocow buffered writes after
snapshotting when low on space"

There's a situation where the directory structure and the inobt
thinks the inode is free, but the inode on disk thinks it is still
in use. XFS should detect it and prevent the kernel from oopsing on

Since commit a79a464d5675 ("btrfs: Allow rmdir(2) to delete an empty
subvolume"), rm -r can delete a subvolume too.
This test assumes that rm -r does not delete a subvolume.
Currently the commit does not affect the test since qgroup items
still exist after subvolume deletion, but we plan to change the
behavior and remove them along with subvolume deletion.
So update the test and keep subvolume (and qgroup item) in any kernel
version.

So turn to use _scratch_xfs_set_metadata_field, it will help to use

This adds a regression test for the following series:
[PATCH v4 0/2] ext4: fix DAX dma vs truncate/hole-punch
https://lists.01.org/pipermail/linux-nvdimm/2018-July/016842.html
which adds synchronization between DAX DMA in ext4 and truncate/hole-punch.
The intention of the test is to test those specific changes, but it runs
fine both with XFS and without DAX so I've put it in the generic tests
instead of ext4 and not restricted it to only DAX configurations.
When run with v4.18-rc6 + DAX + ext4, this test will hit the following
WARN_ON_ONCE() in dax_disassociate_entry():
WARN_ON_ONCE(trunc && page_ref_count(page) > 1);
If you change this to a WARN_ON() instead, you can see that each of the
four paths being exercised in this test hits that condition many times in
the one second that the subtest is being run.

For example, in en_US.UTF-8 locale, [a-z] means aAbBcCdD...zZ, it

This test tries to make the filesystem go down by setting up
dm-error and committing metadata updates. Since the test doesn't
remount the fs after it goes down to recover the log, this can
result in a dirty log being presented to the post-test filesystem
check if the filesystem is xfs and quotas are enabled.
Since this is a regression test for a NULL pointer dereference in
the kernel after the fs goes down, simply skip the post-test fsck.

If a user constructs a test that loops repeatedly over below steps
on dm-thin, block allocation can fail due to discards not having
completed yet (Fixed by a685557 dm thin: handle running out of data
space vs concurrent discard):
1) fill thin device via filesystem file
2) remove file
3) fstrim
And this maybe cause a deadlock (fast device likes ramdisk can help
a lot) when racing a fstrim with a filesystem (XFS) shutdown. (Fixed
by 8c81dd46ef3c Force log to disk before reading the AGF during a
fstrim)
This case can reproduce both two bugs if they're not fixed. If only
the dm-thin bug is fixed, then the test will pass. If only the fs
bug is fixed, then the test will fail. If both of bugs aren't fixed,
the test will hang.

This is a long existing bug (from 2012) but exposed by a reporter
recently, that when compressed extent without data csum get written
to device-replace target device, the written data is in fact
uncompressed data other than the original compressed data.
And since btrfs still consider the data is compressed and will try
to read it as compressed, it can cause read error.

If you install with:
sudo make install
Depending on the system, you may see that /var/lib/xfstests/
installed properly but /var/lib/xfstests/tests/ is empty and so your
install really is broken and not functional. Finding out what went
wrong is not obvious.
The issue is caused due to the fact that $(PWD) is used nad if sudo
is used this can be empty on some systems.
PWD is only used on one target on the xfstests build system, the
tests/*/ dir install target.
We can fix this by using $(CURDIR) instead.
This issue is observed on both Fedora and OpenSUSE, but not on
Debian.
