Hi all!

Here are some good refactoring and fix of bitmap merge paths.

Vladimir Sementsov-Ogievskiy (4):
  block: bdrv_merge_dirty_bitmap: add return value
  block: block_dirty_bitmap_merge(): fix error path
  block: improve block_dirty_bitmap_merge(): don't allocate extra bitmap
  block: simplify handling of try to merge different sized bitmaps
