From a2e102cd3cdd8b7a14e08716510707b15802073f Mon Sep 17 00:00:00 2001 From: Eric W. Biederman Date: Thu, 22 Mar 2018 21:34:44 -0500 Subject: shm: Move struct shmid_kernel into ipc/shm.c All of the users are now in ipc/shm.c so make the definition local to that file to make code maintenance easier. AKA to prevent rebuilding the entire kernel when struct shmid_kernel changes. Signed-off-by: "Eric W.
