Key:
[----] : patches are identical
[####] : number of functional differences between upstream/downstream patch
[down] : patch is downstream-only
The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively

003/10:[----] [--] 'tests: Add test code for meta bitmap'
004/10:[0004] [FC] 'block: Support meta dirty bitmap'
005/10:[----] [--] 'block: Add two dirty bitmap getters'
006/10:[----] [--] 'block: Assert that bdrv_release_dirty_bitmap succeeded'

010/10:[----] [--] 'block: More operations for meta dirty bitmap'
===
v8: Hello, is it v8 you're looking for?
===
01: Rebase conflict over int64_t header for bdrv_reset_dirty_bitmap.
04: Revised sector math to make literally any sense.
08: Rebase conflict over int64_t header for bdrv_reset_dirty_bitmap.
===
v7:
===
02: Fix rebase mishap.
04: Slight loop adjustment.
09: Fix constant on 32bit machines.
===
v6: Rebase. Stole series from Fam.
===
02: Added documentation changes as suggested by Max.
===
v5: Rebase: first 5 patches from last revision are already merged.
===
Addressed Max's comments:
01: - "block.c" -> "block/dirty-bitmap.c" in commit message.
- "an BdrvDirtyBitmapIter" -> "an BdrvDirtyBitmapIter" in code comment.
- hbitmap_next => next_dirty as variable name.
- bdrv_dirty_iter_free()/bdrv_dirty_iter_new() pairs =>
bdrv_set_dirty_iter.
02: Move the assert fix into 01.
04: Truncate the meta bitmap (done by hbitmap_truncate).
06: Add Max's r-b.
07: I left the memcpy vs cpu_to_le32/64w as is to pick up Max's r-b. That
could be improved on top if wanted.
10: Add Max's r-b.
