From 4d7a55f5b8099224e250e5e87882e4d7168af129 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Sat, 30 Sep 2017 19:46:48 +0800 Subject: [PATCH] dm mpath: remove annoying message of 'blk_get_request() returned -11' commit 9dc112e2daf87b40607fd8d357e2d7de32290d45 upstream. It is very normal to see allocation failure, especially with blk-mq request_queues, so it's unnecessary to report this error and annoy people. In practice this 'blk_get_request() returned -11' error gets logged quite frequently when a blk-mq DM multipath device sees heavy IO. This change is marked for stable@ because the annoying message in question was included in stable@ commit 7083abbbf.
