[PATCH] ipc: add generic struct ipc_ids seq_file iteration
The following two patches convert /proc/sysvipc/* to use seq_file. This gives us the following: - Self-consistent IPC records in proc. - O(n) reading of the files themselves. This patch: Add a generic method for ipc types to be displayed using seq_file. This patch abstracts out seq_file iterating over struct ipc_ids into ipc/util.c Signed-off-by: Mike Waychison <mikew@google.com> Cc: Manfred Spraul <manfred@colorfullife.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
