Will splitting REQ_META in two will help. Say REQ_META_SYNC and
REQ_META_ASYNC. So meta requests which don't require any kind of priority
boost at CFQ can mark these REQ_META_ASYNC (XFS).
- So we retain the capability to mark metadata requests
- Priority boost only for selected meta data.
- Throttling can use this to avoid throttling meta data.
Thanks
