Wasn't this in the last patch?

It seems kinda strange that the user/group quota inode number has to be
below 2^32 yet the project quota inode doesn't have this restriction?
Oh, right, the user/group quota are supposed to be inum 3 and 4 whereas
the project inode number can float. Never mind.

quota_set_sb_inum and quota_sb_inum?
How about quota_{get,set}_sb_inum since they're a pair?
