shared/272 fails with kernels v4.15-rc1 and beyond when you are mounted
with DAX:
shared/272 [failed, exit status 1] - output mismatch (see
/root/project/xfstests/results//shared/272.out.bad)

This is expected. The following kernel commit:
commit e9072d859df3 ("ext4: prevent data corruption with journaling + DAX")
makes "chattr +j", which is attempting to turn on data journaling, return
-EBUSY if the ext4 DAX mount option is in use. This was done to prevent
the data corruption shown in xfstest ext4/030, added by this xfstests
commit:
commit 750a24e99e48 ("ext4: test for DAX + journaling corruption")
So, just skip shared/272 if the DAX mount option is in use.
