v4: Rebase.
Add rev-by from John in patches 1-5, 7, 8.
Remove BdrvDirtyBitmap typedef from dirty-bitmap.h in patch 4. [Max]
Add assertion on bm->meta in patch 9. [John]
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
