Subject: [PATCH -next 1/2] ipc/mqueue: remove redundant wq task assignment
Date:   Thu, 21 Mar 2019 12:02:15 -0700
Message-Id: <20190321190216.1719-1-dave@stgolabs.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

We already store the current task fo the new waiter before calling
wq_sleep() in both send and recv paths. Trivially remove the redundant
assignment.
