[Qemu-block] [PATCH for-2.12 0/4] qmp dirty bitmap API

[Vladimir Sementsov-Ogievskiy]

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

Question: it may be better to make one command instead of two:
block-dirty-bitmap-set-enabled(bool enabled)

Vladimir Sementsov-Ogievskiy (4):
  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
