So basically you want a variant of get_super() that would get you a
superblock for this bdev, locked and unfrozen?  Fair enough, but
	* that should be a proper helper in super.c, rather than
open-coded in fs/quota/quota.c, of all places
	* what about other existing callers get_super() and its friends?

and while we are at it, why in damnation name is it exported?  The only
caller outside of core VFS is under #if 0...
