With kernel commit b353756b2b71 ("kmemleak: always register debugfs
file") that was merged to v4.19-rc3, the kmemleak debugfs knob
exists even if kmemleak is disabled, but returns EBUSY on write.
Suppress EBUSY errors in tests by disabling _check_kmemleak() calls
if the write to kmemleak knob failed on _init_kmemleak().

Originally this test case was designed to work with 4K sectorsize.
Now enhance it to work with any sector sizes and makes the following
changes:
.out file not to contain any traces of sector size.
Use max_inline=0 mount option so that it meets the requisite of non inline
regular extent.
Don't log the md5sum results to the output file as the data size vary by
the sectorsize.

The purpose of OVL_BASE_FSTYP is to store the value of FSTYP that is
found in a host config file section.
When there is no host config file or if user sets FSTYP=overlay in config
file, it makes no sense to store the value "overlay" in OVL_BASE_FSTYP
and it is better to leave it empty or leave its current value in tact.
This allows user to set OVL_BASE_FSTYP in config file or before running
the test to support queries about base fs, such as
_require_metadata_journaling, even when running an overlay test.

This bug is exposed by populating a high level qgroup, and then make
it childless with old qgroup numbers, and finally do rescan.
Normally rescan should zero out all qgroups' accounting number, but
due to a kernel bug which won't mark childless qgroups dirty, their
on-disk data is never updated, thus old numbers remain and cause
qgroup corruption.
Fixed by the following kernel patch:
"btrfs: qgroup: Dirty all qgroups before rescan"

Since glibc 2.28 has added the statx function after commit
fd70af45528d ("Add the statx function"), stat_test.c will include

causes the STATX_TYPE has already been defined before include
"status.h", then xfstests_statx will not be defined.

Currently the commit does not affect the test since qgroup items
still exist after subvolume deletion, but we plan to change the

So update the test and keep subvolume (and qgroup item) in any kernel

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.
