Subject: [PATCH v6 16/16] nvmet-passthru: support block accounting
Date: Thu, 25 Jul 2019 11:23:35 -0600 [thread overview]
Message-ID: <20190725172335.6825-17-logang@deltatee.com> (raw)
In-Reply-To: <20190725172335.6825-1-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.
