Hi all.
There are three qmp commands, needed to implement external backup API.
Using these three commands, client may do all needed bitmap management by
hand:
on backup start we need to do a transaction:
{disable old bitmap, create new bitmap}
on backup success:
drop old bitmap
on backup fail:
enable old bitmap
merge new bitmap to old bitmap
drop new bitmap
v2: fix merge command deadlock
add new patches: 1 and 6
Vladimir Sementsov-Ogievskiy (6):
block: maintain persistent disabled bitmaps
block/dirty-bitmap: add lock to bdrv_enable/disable_dirty_bitmap
qapi: add block-dirty-bitmap-enable/disable
qmp: transaction support for block-dirty-bitmap-enable/disable
qapi: add block-dirty-bitmap-merge
qapi: add disabled parameter to block-dirty-bitmap-add
