Subject: [PATCH -next 1/2] ipc/mqueue: remove redundant wq task assignment
Date: Thu, 21 Mar 2019 12:02:15 -0700	[thread overview]
Message-ID: <20190321190216.1719-1-dave@stgolabs.net> (raw)

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.
