[Qemu-devel] [PATCH 00/13] Dirty bitmap changes for migration/persistence work

[Fam Zheng <famz@redhat.com>]

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 (11):
  backup: Use Bitmap to replace "s->bitmap"
  typedefs: Add BdrvDirtyBitmap and HBitmapIter
  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

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