From 614b84cf4e4a920d2af32b8f147ea1e3b8c27ea6 Mon Sep 17 00:00:00 2001 From: "Serge E. Hallyn" Date: Mon, 6 Apr 2009 19:01:08 -0700 Subject: namespaces: mqueue ns: move mqueue_mnt into struct ipc_namespace Move mqueue vfsmount plus a few tunables into the ipc_namespace struct. The CONFIG_IPC_NS boolean and the ipc_namespace struct will serve both the posix message queue namespaces and the SYSV ipc namespaces. The sysctl code will be fixed separately in patch 3. After just this patch, making a change to posix mqueue tunables always changes the values in the initial ipc namespace. Signed-off-by: Cedric Le Goater Signed-off-by: Serge E.
