Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Al Viro says:

====================
netdev-related stuff in vfs.git

There are several commits sitting in vfs.git that probably ought to go in
via net-next.git.  First of all, there's merge with vfs.git#iocb - that's
Christoph's aio rework, which has triggered conflicts with the ->sendmsg()
and ->recvmsg() patches a while ago.  It's not so much Christoph's stuff
that ought to be in net-next, as (pretty simple) conflict resolution on merge.
The next chunk is switch to {compat_,}import_iovec/import_single_range - new
safer primitives for initializing iov_iter.  The primitives themselves come
from vfs/git#iov_iter (and they are used quite a lot in vfs part of queue),
conversion of net/socket.c syscalls belongs in net-next, IMO.  Next there's
afs and rxrpc stuff from dhowells.  And then there's sanitizing kernel_sendmsg
et.al.  + missing inlined helper for "how much data is left in msg->msg_iter" -
this stuff is used in e.g.  cifs stuff, but it belongs in net-next.

That pile is pullable from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-davem

I'll post the individual patches in there in followups; could you take a look
and tell if everything in there is OK with you?
