 Ext4 regression fixes for 3.4
 
 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
 to zero.  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.
