Subject: [PATCH 1/9] futex: Remove unused uaddr2 in restart_block
Date: Mon, 9 Sep 2019 11:23:32 +0100 [thread overview]
Message-ID: <20190909102340.8592-2-dima@arista.com> (raw)
In-Reply-To: <20190909102340.8592-1-dima@arista.com>
Not used since introduction in commit 52400ba94675 ("futex: add
requeue_pi functionality").
The result union stays the same size, so nothing saved in task_struct,
but still one __user pointer less to keep.
