Looks good, but I'd really prefer to split this up further:

 - one patch for adding xfs_inode_dquot
 - one patch for adding XFS_IS_TYPE_QUOTA_ON
   (which I'd rather make an inline and call xfs_this_quota_on)
 - one for passing the mount structure to xfs_sb_from_disk
 - one for the quota flags changes.

All of these also should have a good changelog, most importantly the flag
changes.  If you can repost just these changes relatively soon please do
so, as I have a huge series for the quota code that should go into the
3.2 tree which I need to rebase anyway, and I'd like to do it on top of
your changes.

For code you touch please always use the struct versions instead of
the typedefs for lines you change anyway or add.
