Currently, it requires that not only\nthe top and base node of the commit operation are specified, but also\nthe active layer of the backing file chain. Of course, the assumption\nthat a single active layer exists is invalid.\n\nThis series makes the commit job consider other roots as well so that\nall parent nodes of the top node get their backing file updated and stay\nvalid after the commit job completes.\n\nWith this, we should have all of the prerequisites for a follow-up\nseries that adds a new and clean blockdev-commit QMP command which\ndoesn't require an option for the active layer and which accepts node\nnames instead of file names for base and top.\n\nKevin Wolf (5):\n block: Introduce BdrvChildRole.update_filename\n commit: Support multiple roots above top node\n qemu-iotests: Allow QMP pretty printing in common.qemu\n qemu-iotests: Test commit block job where top has two parents\n commit: Remove overlay_bs\n\n include/block/block.h | 3 +-\n include/block/block_int.h | 6 +\n block.c | 91 +++--\n block/commit.c | 64 +---\n tests/qemu-iotests/030 | 4 -\n tests/qemu-iotests/191 | 152 ++++++++\n tests/qemu-iotests/191.out | 827 +++++++++++++++++++++++++++++++++++++++++\n tests/qemu-iotests/common.qemu | 14 +-\n tests/qemu-iotests/group | 1 +\n 9 files changed, 1078 insertions(+), 84 deletions(-)\n create mode 100755 tests/qemu-iotests/191\n create mode 100644 tests/qemu-iotests/191.out"}
