[PATCH v7 14/14] nvmet-passthru: support block accounting

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
