From c0371da6047abd261bc483c744dbc7d81a116172 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 24 Nov 2014 10:42:55 -0500 Subject: put iov_iter into msghdr Note that the code _using_ ->msg_iter at that point will be very unhappy with anything other than unshifted iovec-backed iov_iter. We still need to convert users to proper primitives.
