Subject: [PATCH 3/8] padata: Remove superfluous might_sleep
Date: Thu, 29 Apr 2010 14:40:53 +0200 [thread overview]
Message-ID: <20100429124053.GG5275@secunet.com> (raw)
In-Reply-To: <20100429123636.GD5275@secunet.com>
might_sleep() was placed before mutex_lock() in some places.
We remove them because mutex_lock() does might_sleep() too.
