Subject: [PATCH] ipc/mqueue: simplify reading msgqueue limit
Date: Thu, 03 Nov 2011 15:31:49 -0300 [thread overview]
Message-ID: <1320345109.3188.3.camel@offbook> (raw)
From: Davidlohr Bueso <dave@gnu.org>
Because the current task is being used to get the limit, we can simply use rlimit() instead of task_rlimit().
