[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
