[Qemu-devel] [PATCH v7 00/10] Dirty bitmap changes for migration/persistence work

[John Snow <jsnow@redhat.com>]

v7:

   02: Fix rebase mishap.
   04: Slight loop adjustment.
   09: Fix constant on 32bit machines.

v6: Rebase.

    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.
