[Qemu-block] [PATCH v2 0/6] 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

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
