Hi all!
We need to lock qcow2 mutex on accessing in-image metadata, especially
on updating this metadata. Let's implement it.
v3:
01: add John's r-b
02: - fix bdrv_remove_persistent_dirty_bitmap return value
- drop extra zeroing of ret in qcow2_remove_persistent_dirty_bitmap
03: add John's r-b
Vladimir Sementsov-Ogievskiy (3):
block: move bdrv_can_store_new_dirty_bitmap to block/dirty-bitmap.c
block/dirty-bitmap: return int from
bdrv_remove_persistent_dirty_bitmap
block/qcow2: proper locking on bitmap add/remove paths
