This is the final patch series that is required before we can start allowing setups with more than one BlockBackend per BlockDriverState.
My current plan is to put the patches up to (and including) this series into 2.6 so that we have a relatively consistent block layer state in the release that isn't in the middle of an overhaul, but not to make use of the new setups that we could allow now before 2.7. Depends on 'block: Move I/O throttling to BlockBackend'. Kevin Wolf (9): block: Use BdrvChild callbacks for change_media/resize block: User BdrvChild callback for device name block jobs: Use BdrvChild callbacks for iostatus operations block: Remove bdrv_aio_multiwrite() block: Avoid BDS.blk in bdrv_next() block: Remove bdrv_move_feature_fields() block: Avoid bs->blk in bdrv_next() block: Don't return throttling info in query-named-block-nodes block: Remove BlockDriverState.blk block.c | 130 +++++++++++--------------- block/backup.c | 20 ++-- block/block-backend.c | 142 ++++++++++++++++++++-------- block/commit.c | 2 +- block/io.c | 207 ++--------------------------------------- block/mirror.c | 25 +++-- block/qapi.c | 6 +- block/snapshot.c | 30 +++--- block/stream.c | 2 +- blockdev.c | 22 ++--- blockjob.c | 85 ++++++++++++++++- include/block/block.h | 10 +- include/block/block_int.h | 17 +++- include/block/blockjob.h | 9 ++ include/sysemu/block-backend.h | 3 +- migration/block.c | 4 +- monitor.c | 6 +- qemu-io-cmds.c | 203 ---------------------------------------- qmp.c | 5 +- tests/qemu-iotests/085.out | 6 +- tests/qemu-iotests/096 | 3 +- tests/qemu-iotests/100 | 146 ----------------------------- tests/qemu-iotests/100.out | 89 ------------------ tests/qemu-iotests/136 | 20 +--- tests/qemu-iotests/136.out | 4 +- tests/qemu-iotests/group | 2 +- trace-events | 2 - 27 files changed, 353 insertions(+), 847 deletions(-) delete mode 100755 tests/qemu-iotests/100 delete mode 100644 tests/qemu-iotests/100.out -- 1.8.3.1
