Any objections to this patch? >From cfecafff4d4b1bb0f8fd49eb8e19384b34a7dc22 Mon Sep 17 00:00:00 2001 From: Serge E. Hallyn <[email protected]> Date: Mon, 2 Mar 2009 16:40:18 -0800 Subject: [PATCH 1/1] ipc namespace: initialize init_ipc_ns.count to 1
That's one count for the init task. Nothing else pins an ipc ns (i.e. not ipcns->mq_mnt). The only references to init_ipc_ns are the sysctl .data calculations, which should remain safe.
