Apart from renaming 'x-blockdev-reopen' into 'blockdev-reopen', the remaining functional change in this series is taking a list of nodes to reopen as an argument so that multiple changes to the graph can be made atomically that would be invalid separately (e.g. due to permission checks on the intermediate state). It also contains a qcow2 fix for a bug introduced by the part of the series that was already picked up in Vladimir's "[PATCH v6 0/9] Allow changing bs->file on reopen". v6: - Changed qcow2 fix to set s->data_file = NULL between .prepare and .commit instead of using a separate bool [Vladimir] - Coding style fixes [Vladimir] Alberto Garcia (4): block: Add bdrv_reopen_queue_free() block: Support multiple reopening with x-blockdev-reopen iotests: Test reopening multiple devices at the same time block: Make blockdev-reopen stable API Kevin Wolf (2): qcow2: Fix dangling pointer after reopen for 'file' block: Acquire AioContexts during bdrv_reopen_multiple() qapi/block-core.json | 24 +++--- include/block/block.h | 3 + block.c | 71 +++++++++++++---- block/qcow2.c | 29 +++++++ block/replication.c | 7 ++ blockdev.c | 76 ++++++++++-------- qemu-io-cmds.c | 7 +- tests/qemu-iotests/155 | 9 ++- tests/qemu-iotests/165 | 4 +- tests/qemu-iotests/245 | 78 +++++++++++++++---- tests/qemu-iotests/245.out | 4 +- tests/qemu-iotests/248 | 4 +- tests/qemu-iotests/248.out | 2 +- tests/qemu-iotests/296 | 11 ++- tests/qemu-iotests/298 | 4 +- .../tests/remove-bitmap-from-backing | 22 +++--- 16 files changed, 255 insertions(+), 100 deletions(-) -- 2.31.1
