[PATCH 19/28] blk_end_request: changing scsi (take 3)

From: Kiyoshi Ueda
Date: Fri Nov 30 2007 - 18:33:27 EST


This patch converts scsi mid-layer to use blk_end_request().

The comment above scsi_next_command() is not related to this change.
It had originally been there before scsi_next_command() was included
in scsi_finalize_request().
