[Qemu-devel] [PATCH 0/5] block/dirty-bitmap: check number and size constraints against queued bitmaps

[John Snow]

When adding new persistent dirty bitmaps, we only check constraints
against currently stored bitmaps, and ignore the pending number and size
of any bitmaps yet to be stored.

Rework the "can_store" and "remove" interface to explicit "add" and "remove",
and begin keeping track of the queued burden when adding new bitmaps.
