[Qemu-devel] [PATCH 0/6] dirty-bitmap: rewrite bdrv_dirty_iter_next_area

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

Hi all.

1. bdrv_dirty_iter_next_area don't use hbitmap_next_zero and uses
inefficient loop instead. Let's improve it.

2. bdrv_dirty_iter_next_area don't handle unaligned offset and
max_offset correctly. I'm not sure that it is a real bug. But if it is,
we need these series in 3.0.

Details are in 03 commit message.
