[Qemu-block] [PATCH v3 0/4] transaction support for bitmap merge

[Vladimir Sementsov-Ogievskiy]

This is a last brick, necessary to play with nbd bitmap export in
conjunction with image fleecing.

v3:
01: fix type in commit message, add John's r-b
02: splitted refactoring
03: improve commit message, split some refactoring to 02
04: add John's r-b
05: drop extra state variable, make it local instead. John's r-b.


v2: don't compare with v1, it is changed a lot, to do the whole thing
    in .prepare instead of .commit. It is needed to be compatible with
    backup block job transaction actions [John]

Vladimir Sementsov-Ogievskiy (5):
  dirty-bitmap: switch assert-fails to errors in bdrv_merge_dirty_bitmap
  dirty-bitmap: rename bdrv_undo_clear_dirty_bitmap
  dirty-bitmap: make it possible to restore bitmap after merge
  blockdev: rename block-dirty-bitmap-clear transaction handlers
  qapi: add transaction support for x-block-dirty-bitmap-merge
