Subject: [PATCH 08/24] nsp_cs.c convert to data accessors and !use_sg cleanup
Date: Wed, 12 Sep 2007 02:56:45 +0300 [thread overview]
Message-ID: <46E72B3D.7060408@panasas.com> (raw)
In-Reply-To: <46E6F92D.2090409@panasas.com>
- use scsi data accessors
- cleanup !use_sg code paths
- TODO: use next_sg() for Jens's sglist branch. Look for 2
places with "SCp.buffer++"
