From 8f5280f4ee75333ca12bde99ef6280ff65a8af43 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 13 Jun 2014 19:43:04 +0200 Subject: [PATCH] blk-mq: properly drain stopped queues If we need to drain a queue we need to run all queues, even if they are marked stopped to make sure the driver has a chance to error out on all queued requests. This fixes surprise removal with scsi-mq.
