Subject: [PATCH 01/15] libata: make atapi_request_sense() use sg
Date: Wed, 5 Dec 2007 16:43:01 +0900 [thread overview]
Message-ID: <11968405951137-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11968405951262-git-send-email-htejun@gmail.com>
atapi_request_sense() is now the only left user of ata_sg_init_one().
Convert it to use sg interface.
