PS: there's a large pending series reworking the refcounting and lifetime
rules for vfsmounts that will, among other things, allow to rip a subtree
away _without_ dissolving connections in it, to be garbage-collected
when all active references are gone.  It's considerably saner wrt "is
the subtree busy" logics, but it's nowhere near being ready for merge
at the moment; this changeset is one of the things becoming possible
with that sucker, but it certainly shouldn't have been picked during this
cycle.  My apologies...
