== SRU Request [ Trusty, Xenial, Yakkey ] + Zesty
When running the stress-ng --xattr stressor with several instances of the stressor on ext4 we can trip an xattr bug in the ext4 file system.
== Fix ==
Upstream commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dac7a4b4b1f664934e8b713f529b629f67db313c
ext4: lock the xattr block before checksuming it
We must lock the xattr block before calculating or verifying the
checksum in order to avoid spurious checksum failures.

Reported-by: Colin Ian King <colin.king@canonical.com>
Signed-off-by: Theodore Ts'o <tytso@mit.edu>
Cc: stable@vger.kernel.org
== Test case ==
Fire up an x86 VM with 8 or more CPUs in the instance, run:
stress-ng --xattr 0 -t 60 -v
Without the fix, the file system will report broken xattrs and the file system will go read-only.
With the fix, it runs without fault.
== Regression Potential ==
This changes the checksumming in the ext4 xattr so it only touches the ext4 xattr part of the file system. Risk is therefore contained in the xattr handling on ext4. Tested with stress-ng and the generic file system tests without any regressions, so risk is limited and small.
