3.8.13.7 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Theodore Ts'o <tytso@mit.edu>

commit 59d9fa5c2e9086db11aa287bb4030151d0095a17 upstream.

Commit 26092bf ("ext4: use a table-driven handler for mount options")
wrongly disallows the specifying the mount options nodelalloc and
data=journal simultaneously.  This is incorrect; it should have only
disallowed the combination of delalloc and data=journal
simultaneously.
