From 4d6062193b4ca53bb45a318a1ec7680fd91b72ad Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 17 Aug 2017 16:23:00 -0700 Subject: [PATCH] block: Fix two comments that refer to .queue_rq() return values Since patch "blk-mq: switch .queue_rq return value to blk_status_t" .queue_rq() returns a BLK_STS_* value instead of a BLK_MQ_RQ_* value. Hence refer to the former in comments about .queue_rq() return values.
