[PATCH v4 00/18] bitmaps: introduce 'bitmap' sync mode
This follows the previous series which adds the 'bitmap' sync mode
and uses it to add interactions with bitmaps to the 'full' and 'top'
modes to blockdev-backup and drive-backup.
on-success: Can conveniently synchronize a bitmap to a full backup.
Allows for transactionless anchor backups.
Allows us to attempt an anchor backup without damaging
our bitmap until the backup is successful.
Allows for transactional, ungrouped anchor backups.
always: Allows us to resume full/top style backups with a later
invocation to sync=bitmap. Neat!
1-3: Refactor iotest 257 to accommodate this;
4-5: Augment 257 to test trivial failure cases
6-7: Implement feature
8: Test new feature
John Snow (8):
iotests/257: add Pattern class
iotests/257: add EmulatedBitmap class
iotests/257: Refactor backup helpers
block/backup: hoist bitmap check into QMP interface
iotests/257: test API failures
block/backup: issue progress updates for skipped regions
block/backup: support bitmap sync modes for non-bitmap backups
iotests/257: test traditional sync modes
