Subject: [PATCH 01/10] dmatest: cancel thread immediately when asked for
Date: Mon, 4 Mar 2013 11:09:25 +0200 [thread overview]
Message-ID: <1362388174-3435-2-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1362388174-3435-1-git-send-email-andriy.shevchenko@linux.intel.com>
If user have the timeout alike issues and wants to cancel the thread
immediately, the current call of wait_event_freezable_timeout is preventing to
this until timeout is expired. Thus, user will experience the unnecessary
delays.
Adding kthread_should_stop() check inside wait_event_freezable_timeout() solves
that.
