From 5e955245d6cf49c5ed26c7add7392ff5a6762bf4 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 23 Jun 2009 11:27:27 +0000 Subject: [PATCH] ide: always kill the whole request on error * Use blk_rq_bytes() instead of obsolete ide_rq_bytes() in ide_kill_rq() and ide_floppy_do_request() for failed requests. [ bugfix part ] * Use blk_rq_bytes() instead of obsolete ide_rq_bytes() in ide_do_devset() and ide_complete_drive_reset(). Then remove ide_rq_bytes().
