[PATCH v2 00/10] Further bitmaps improvements

[Vladimir Sementsov-Ogievskiy]

Hi!

The main feature here is improvement of _next_dirty_area API, which I'm
going to use then for backup / block-copy.

v2:
01: just use INT64_MAX instead of adding new constant
08: add separate function nbd_extent_array_convert_to_be and converted
    state of NBDExtentArray, to make these things explicit, and avoid
    extra memdup.
09: Save part of comment for bitmap_to_extents(), add Eric's r-b

Vladimir Sementsov-Ogievskiy (10):
  hbitmap: assert that we don't create bitmap larger than INT64_MAX
  hbitmap: move hbitmap_iter_next_word to hbitmap.c
  hbitmap: unpublish hbitmap_iter_skip_words
  hbitmap: drop meta bitmaps as they are unused
  block/dirty-bitmap: switch _next_dirty_area and _next_zero to int64_t
  block/dirty-bitmap: add _next_dirty API
  block/dirty-bitmap: improve _next_dirty_area API
  nbd/server: introduce NBDExtentArray
  nbd/server: use bdrv_dirty_bitmap_next_dirty_area
  block/qcow2-bitmap: use bdrv_dirty_bitmap_next_dirty
