Subject: [PATCH v8 13/13] nvmet-passthru: support block accounting
Date: Wed, 28 Aug 2019 15:54:29 -0600 [thread overview]
Message-ID: <20190828215429.4572-14-logang@deltatee.com> (raw)
In-Reply-To: <20190828215429.4572-1-logang@deltatee.com>
Support block disk accounting by setting the RQF_IO_STAT flag
and gendisk in the request.
After this change, IO counts will be reflected correctly in
/proc/diskstats for drives being used by passthru.
