Revert "fix mismerge with Trond's stuff (create_mnt_ns() export is gone now)"
This reverts commit e9496ff46a20a8592fdc7bdaaf41b45eb808d310. Quoth Al:
"it's dependent on a lot of other stuff not currently in mainline
and badly broken with current fs/namespace.c. Sorry, badly
out-of-order cherry-pick from old queue.
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..."
