From 34b56df922b10ac2876f268c522951785bf333fd Mon Sep 17 00:00:00 2001 From: Eric W. Biederman Date: Thu, 22 Mar 2018 21:37:34 -0500 Subject: msg: Move struct msg_queue into ipc/msg.c All of the users are now in ipc/msg.c so make the definition local to that file to make code maintenance easier. AKA to prevent rebuilding the entire kernel when struct msg_queue changes. Signed-off-by: "Eric W.
