From 283369ccc26705bd9585a0e533c92bd7364c28d1 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 24 Apr 2005 02:06:36 -0500 Subject: [PATCH] [SCSI] make scsi_requeue_request() use blk_requeue_request() scsi_requeue_request() used to use blk_insert_request() for requeueing requests. This depends on the unobvious behavior of blk_insert_request() setting REQ_SPECIAL and REQ_SOFTBARRIER when requeueing. This patch makes scsi_queue_insert() use blk_requeue_request(). As REQ_SPECIAL means special requests and REQ_SOFTBARRIER is automatically handled by blk layer now, no flag needs to be set.
