Subject: [PATCH 9/32] nsp_cs.c convert to data accessors and !use_sg cleanup
Date: Wed, 17 Oct 2007 19:43:36 +0200 [thread overview]
Message-ID: <471649C8.20809@panasas.com> (raw)
In-Reply-To: <47164306.6090702@panasas.com>
[PATCH 9/32] nsp_cs.c convert to data accessors and !use_sg cleanup
- 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++"
