From fc17b6534eb8395f0b3133eb31d87deec32c642b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 3 Jun 2017 09:38:05 +0200 Subject: blk-mq: switch ->queue_rq return value to blk_status_t Use the same values for use for request completion errors as the return value from ->queue_rq. BLK_STS_RESOURCE is special cased to cause a requeue, and all the others are completed as-is.
