The first part of mount updates. It's messier than I'd like;
the branch itself merges with a couple of trivial conflicts, but there
are two filesystems that have grown the need of update while in
separate branches. I can do backmerges for those two (dmabuf and
vmballon), but fixups required are rather trivial. Not sure what
would be the best way to deal with that; it could be folded into
the merge commit, but...

Anyway, I'd pushed the proposed conflict resolution into
#merge-candidate, with followups in separate commit on top of the
merge; folding that into the merge itself is trivial. Up to you.
FWIW, the fixup itself (as had been done in -next) amounts to

and it's basically conversions of two pseudo-filesystems to
init_pseudo().
