From ea73a9f23906c374b697cd5b0d64f6dceced63de Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sun, 28 Aug 2005 11:33:52 -0500 Subject: [SCSI] convert sd to scsi_execute_req (and update the scsi_execute_req API) This one removes struct scsi_request entirely from sd. In the process, I noticed we have no callers of scsi_wait_req who don't immediately normalise the sense, so I updated the API to make it take a struct scsi_sense_hdr instead of simply a big sense buffer.
