Subject: [PATCH] scsi: default to scsi-mq
Date: Fri, 16 Jun 2017 10:27:55 +0200 [thread overview]
Message-ID: <20170616082755.22832-1-hch@lst.de> (raw)
Remove the SCSI_MQ_DEFAULT config option and default to the blk-mq I/O
path now that we had plenty of testing, and have I/O schedulers for
blk-mq. The module option to disable the blk-mq path is kept around
for now.
