Fabian Grünbichler (2): mirror: move some checks to qmp iotests: add test for bitmap mirror John Snow (2): drive-mirror: add support for sync=bitmap mode=never drive-mirror: add support for conditional and always bitmap sync modes include/block/block_int.h | 4 +- block/mirror.c | 96 +- blockdev.c | 71 +- tests/test-block-iothread.c | 4 +- qapi/block-core.json | 29 +- tests/qemu-iotests/306 | 546 +++++++ tests/qemu-iotests/306.out | 2846 +++++++++++++++++++++++++++++++++++ tests/qemu-iotests/group | 1 + 8 files changed, 3566 insertions(+), 31 deletions(-) create mode 100755 tests/qemu-iotests/306 create mode 100644 tests/qemu-iotests/306.out -- 2.20.1
