And BTW in the highly unlikely case, that something didn't have a
vfsmount and wanted to do some operation, it _should_ definitely just
allocate a kernel-private mount for that.  Why?  Because that means
that another interface, namely the grab-sb-for-write and
release-sb-for-write interfaces won't have to be exported for such
users, resulting in an overall smaller and simpler API.  And that's
good.

Now tell me in small words, why do we need the vfs_ interface to stay
around?
