splice stuff. There are conflicts in lustre; proposed resolution
is in #merge-candidate (same as it is in linux-next). There's a bunch of
branches this cycle, both mine and from other folks and I'd rather send
pull requests separately. This one is the conversion of ->splice_read()
to ITER_PIPE iov_iter (and introduction of such). Gets rid of a lot of
code in fs/splice.c and elsewhere; there will be followups, but these are
for the next cycle... Some pipe/splice-related cleanups from Miklos in
the same branch as well.
The following changes since commit 08895a8b6b06ed2323cd97a36ee40a116b3db8ed:
