From a503bdb6d329a174e4cf31c515f210c75f6c5837 Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Wed, 30 Nov 2011 15:12:05 +1100 Subject: [PATCH] ipc/mqueue: simplify reading msgqueue limit Because the current task is being used to get the limit, we can simply use rlimit() instead of task_rlimit().
