picking up on John's in-progress patch series from last summer, this is
a stab at rebasing and adding test cases for the low-hanging fruits:
- bitmap mirror mode with always/on-success/never bitmap sync mode
- incremental mirror mode as sugar for bitmap + on-success
Fabian Grünbichler (4):
mirror: add check for bitmap-mode without bitmap
mirror: switch to bdrv_dirty_bitmap_merge_internal
iotests: add test for bitmap mirror
mirror: move some checks to QMP
John Snow (2):
drive-mirror: add support for sync=bitmap mode=never
drive-mirror: add support for conditional and always bitmap sync modes
