[Qemu-devel] [PATCH v2 0/3] Bitmap clean-up patches for 2.6

[Fam Zheng <famz@redhat.com>]

v2: bitmap_set -> set_bit. [Congyang, Paolo, John]
    Add John Snow's rev-by with that change.

This makes a cleaner base for more dirty bitmap work. "granularity" appearing
with different representations have always been mind twisting, remove it from
HBitmap to make the interface and implementation simpler. Upon this, it is
a bit easier to add persistent dirty bitmap functionalities.

Block dirty bitmap is not unit-tested, so the removal of HBitmap test code
looks like a loss, but the overall test coverage is barely affected as we also
have various mirror, commit and backup iotest cases, and they do catch various
bugs when I wrote the patches.

Please review!
