Thanks.  After some pondering I think we should setup the iops for the
quota inodes as well - if we ever do something like vfs_getattr on them
now that we're using VFS inode everywhere we'll need it.  And I'd better
be prepared for that than finding bugs after I've forgotten about all
this.  I'll send an incremental patch.
