From 8f4a3809c18ff3107bdbb1fabe3f4e5d2a928321 Mon Sep 17 00:00:00 2001 From: Pierre Peiffer <pierre.peiffer@bull.net> Date: Tue, 29 Apr 2008 01:00:51 -0700 Subject: IPC: introduce ipc_update_perm() The IPC_SET command performs the same permission setting for all IPCs. This patch introduces a common ipc_update_perm() function to update these permissions and makes use of it for all IPCs.
