Subject: [PATCH 1/1] scsi: storvsc: Always use blk-mq
Date: Wed, 19 Dec 2018 18:40:49 +0000 [thread overview]
Message-ID: <1545243282-10573-1-git-send-email-mikelley@microsoft.com> (raw)
With high IOPS storage being increasingly prevalent for guests
on Hyper-V and in Azure, make blk-mq the default so that the
full performance of the storage can be realized without having
to tweak other configuration settings.
