Ouch. Yes, you are right. Oh, shit... We certainly can decide that for
some fs types umount_begin is called always, but that quickly becomes
rather ugly. Linus, your opinion? The problem is obvious - you hold extra
references to dentries, so umounting the nonempty fs is kinda tricky. OTOH
here we really want all inodes to be destroyed... Comments?
