From: Mike Snitzer Date: Thu, 18 Dec 2014 21:26:47 +0000 (-0500) Subject: dm table: train hybrid target type detection to select blk-mq if appropriate X-Git-Tag: fixes-v4.0-rc1~116^2~9 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=65803c205983;p=pandora-kernel.git dm table: train hybrid target type detection to select blk-mq if appropriate Otherwise replacing the multipath target with the error target fails: device-mapper: ioctl: can't change device type after initial table load. The error target was mistakenly considered to be target type DM_TYPE_REQUEST_BASED rather than DM_TYPE_MQ_REQUEST_BASED even if the target it was to replace was of type DM_TYPE_MQ_REQUEST_BASED.
