The big thing in this pile is Eric's unmount-on-rmdir series; we finally
have everything we need for that. The final piece of prereqs is delayed
mntput() - now filesystem shutdown always happens on shallow stack.
Other than that, we have several new primitives for iov_iter (Matt Wilcox,
culled from his XIP-related series) pushing the conversion to ->read_iter()/
->write_iter() a bit more, a bunch of fs/dcache.c cleanups and fixes
(including the external name refcounting, which gives consistent behaviour
of d_move() wrt procfs symlinks for long and short names alike) and
assorted cleanups and fixes all over the place.
This is just the first pile; there's a lot of stuff from various people that
ought to go in this window. Starting with unionmount/overlayfs mess... ;-/
