Biederman <ebiederm@xmission.com> +Date: Fri Sep 7 20:12:54 2012 +0000 + + netlink: Rename pid to portid to avoid confusion + + It is a frequent mistake to confuse the netlink port identifier with a + process identifier. Try to reduce this confusion by renaming fields + that hold port identifiers portid instead of pid. + + I have carefully avoided changing the structures exported to + userspace to avoid changing the userspace API. + + I have successfully built an allyesconfig kernel with this change. + + Signed-off-by: "Eric W.
