Subject: [PATCH 8/8] Get rid of SLAB_DMA
Date: Tue, 28 Nov 2006 16:45:08 -0800 (PST) [thread overview]
Message-ID: <20061129004507.11682.73982.sendpatchset@schroedinger.engr.sgi.com> (raw)
In-Reply-To: <20061129004426.11682.36688.sendpatchset@schroedinger.engr.sgi.com>
Get rid of SLAB_DMA
SLAB_DMA is an alias of GFP_DMA. This is the last one so we
remove the leftover comment too.
