	->sendmsg() side of that business, now.  By the end of it, we
get all ->sendmsg() instances leaving iovec unchanged and ->msg_iter -
drained.

 ...

	The pile after that one will be dealing with the kernel_sendmsg and
kernel_recvmg callers - at that point we can start reaping benefits of
consistent way ->msg_iter is handled.  Note that after these changes if
iov_iter_kvec() is used to initialize ->msg_iter, we don't need the games
with get_fs()/set_fs() anymore; just sock_sendmsg()/sock_recvmsg() will do,
so quite a few of those kernel_{send,recv}msg() callers will turn into
sock_{send,recv}msg() ones.

The content of this series looks fine, but I really would like you
to put proper "subsystem: " prefixes into the commit log header
lines of these commits.

Patch 2 and 3 should use "ipv6: ", patch #4 should use whatever the
name of that device driver "vmw_vmci: " or similar, etc.

Thanks.
