The patch titled ipc: use rlimit helpers has been removed from the -mm tree. Its filename was ipc-use-rlimit-helpers.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: ipc: use rlimit helpers From: Jiri Slaby <jslaby@xxxxxxx> Make sure compiler won't do weird things with limits. E.g. fetching them twice may return 2 different values after writable limits are implemented. I.e. either use rlimit helpers added in 3e10e716abf3c71bdb5d86b8f507f9e72236c9cd ("resource: add helpers for fetching rlimits") or ACCESS_ONCE if not applicable.
