Subject: [PATCH -mm 5/7][AIO] - Make __sigqueue_free() and __sigqueue_alloc() non static
Date: Thu, 1 Feb 2007 10:31:30 +0100	[thread overview]
Message-ID: <20070201103130.406d90cd@frecb000686> (raw)
In-Reply-To: <20070201102252.240130c6@frecb000686>


From: Sébastien Dugué <sebastien.dugue@bull.net>

             Make __sigqueue_alloc() and __sigqueue_free() non static

  Allow subsystems to directly call into __sigqueue_alloc() and __sigqueue_free.
This is used by the AIO signal notification patch.
