From c5c5c86c4f75dc6a247f9f5d940a99119701b4d9 Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Fri, 20 Jan 2012 14:34:01 -0800 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().
