This is another feature that was "logically" part of the BlockBackend, but
implemented as a BlockDriverState feature. It was always kept on top using
swap_feature_fields().
This series moves it to be actually implemented in the BlockBackend, removing
another obstacle for removing bs->blk and allowing multiple BBs per BDS.
Depends on 'block: Implement writethrough in BlockBackend'.
Kevin Wolf (12):
block: Don't disable I/O throttling on sync requests
block: Make sure throttled BDSes always have a BB
block: Introduce BlockBackendPublic
block: throttle-groups: Use BlockBackend pointers internally
block: Convert throttle_group_get_name() to BlockBackend
block: Move throttling fields from BDS to BB
block: Move actual I/O throttling to BlockBackend
block: Move I/O throttling configuration functions to BlockBackend
block: Introduce BdrvChild.opaque
block: Drain throttling queue with BdrvChild callback
block: Decouple throttling from BlockDriverState
block: Don't check throttled reqs in bdrv_requests_pending()
