of length 1 was used.

Add a regression test to check that the boundary test
for the fixed-offset parts of xfs_attr_sf_entry
in xfs_attr_shortform_verify is not off by one.
This can be shown by:
touch file
setfattr -n user.a file
With help from Zorro. Thanks very much.

As this patch has been merged, specify the commit id might be better:)

_check_scratch_fs prints error output if it fails, that will break golden file
and cause failure, so don't need to use the "if .... fi" to check that.

I'd like write this case something like below, just for reference:)
_scratch_mkfs > $seqres.full 2>&1
_scratch_mount
localfile=${SCRATCH_MNT}/testfile
touch $localfile
${SETFATTR_PROG} -n user.a $localfile
# Make sure that changes are written to disk
echo 3 > /proc/sys/vm/drop_caches
sleep 3
# If the target bug isn't fixed, getfattr fails
${GETFATTR_PROG} --absolute-names -n user.a $localfile | _filter_scratch
# Make sure the filesystem isn't corrupted manually
_scratch_unmount
_check_scrach_fs
status=0
exit

Hi,
I 'took' this phrase from 'tests/generic/086', would:
'This test verifies the problem fixed in kernel with commit...' work better for you?
Thanks!
