Pull ext4 regression fixes from Ted Ts'o:
"This fixes a scalability problem reported by Andi Kleen and Tim Chen;
they were quite secretive about the precise nature of their workload,
but they later admitted that it only showed up when they were using a
large sparse file, so the amount of data I/O that was needed was close
I'm not sure how realistic this is and it's only a regression if you
consider changes made since 2.6.39 to be a "regression" vis-a-vis the
policy regarding post-merge window bug fixes, but Linus agreed it was
worth fixing, so I'm including it in this pull request.
This also fixes the journalled quota mount options, which I
accidentally broke while I was cleaning up the mount option handling."
