From e458824f9d32e9bf7700d1eb0d201749af48eee0 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 12 May 2009 08:49:32 +0200 Subject: [PATCH] scsi: fix resid_len mis-conversion in scsi_end_request() Commit c3a4d78c580de4edc9ef0f7c59812fb02ceb037f introduced rq->data_len and converted residual count users to it. While converting, it mistakenly converted scsi_end_request() to finish requests with residual count when it wants to do is fully complete the request. Fix it by using blk_end_request_all() instead. This bug was spotted by Boaz Harrosh.
