Check that suid/sgid bits are cleared on direct write. XFS triggered WARN_ON_ONCE in this case. Patchset from Jan Kara fixed the warning: http://oss.sgi.com/archives/xfs/2014-12/msg00071.html This test is inspired by a test case from Eric Sandeen, and follows the test steps in generic/193. This test requires direct I/O, it's not added to generic/193 but to a new test, so that generic/193 still runs on filesystems don't have direct I/O support.
