Subject: [PATCH 21/33] ext4/046: don't run this test if dioread_nolock not
 supported

From: Darrick J. Wong <djwong@...nel.org>

This test checks that directio reads still work ok if nolock is enabled.
Therefore, if the filesystem driver won't mount with dioread_nolock,
skip the test because its preconditions are not satisfied.
