[PATCH 00/10] Further bitmaps improvements

Posted by Vladimir Sementsov-Ogievskiy 6 years, 1 month ago

Hi!

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

Vladimir Sementsov-Ogievskiy (10):
  hbitmap: introduce HBITMAP_MAX_ORIG_SIZE
  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
