[Fam Zheng <famz@redhat.com>]

v2: Rebase and address comments from John, Eric and Vladimir:

    [02/15] block: Include hbitmap.h in block.h
            Split from the next patch. [Eric]

    [04/15] block: Move block dirty bitmap code to separate files
            Fix long line to keep checkpatch.pl happy. [Vladimir]
            Fix comment (HBitmapIter -> BdrvDirtyBitmapIter). [Vladimir]

    [06/15] block: Hide HBitmap in block dirty bitmap interface
            Add John's rev-by.

    [09/15] block: Support meta dirty bitmap
            granularity -> chunk_size

    [10/15] block: Add two dirty bitmap getters
            Add "const" qualifier in function parameters. [Vladimir]

    [11/15] block: Assert that bdrv_release_dirty_bitmap succeeded
            Rebase and reword commit message.

    [12/15] hbitmap: serialization
            Fix typos and add comment. [John]

    [13/15] block: BdrvDirtyBitmap serialization interface
            Add John's rev-by.

    [14/15] tests: Add test code for hbitmap serialization
            Add John's ack-by.

Two major features are added to block dirty bitmap (and underlying HBitmap) in
this series: meta bitmap and serialization, together with all other supportive
patches.

Both operations are common in dirty bitmap migration and persistence: they need
to find whether and which part of the dirty bitmap in question has changed with
meta dirty bitmap, and they need to write it to the target with serialization.


Fam Zheng (13):
  backup: Use Bitmap to replace "s->bitmap"
  block: Include hbitmap.h in block.h
  typedefs: Add BdrvDirtyBitmap
  block: Move block dirty bitmap code to separate files
  block: Remove unused typedef of BlockDriverDirtyHandler
  block: Hide HBitmap in block dirty bitmap interface
  HBitmap: Introduce "meta" bitmap to track bit changes
  tests: Add test code for meta bitmap
  block: Support meta dirty bitmap
  block: Add two dirty bitmap getters
  block: Assert that bdrv_release_dirty_bitmap succeeded
  tests: Add test code for hbitmap serialization
  block: More operations for meta dirty bitmap

Vladimir Sementsov-Ogievskiy (2):
  hbitmap: serialization
  block: BdrvDirtyBitmap serialization interface
