Revision 614b84cf4e4a920d2af32b8f147ea1e3b8c27ea6 authored by Serge E. Hallyn on 07 April 2009, 02:01:08 UTC, committed by Linus Torvalds on 07 April 2009, 15:31:09 UTC 
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.
