Message-ID: <20190910162724.79574-1-vsementsov@virtuozzo.com> (raw)
We need to lock qcow2 mutex on accessing in-image metadata, especially
on updating this metadata. Let's implement it.
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
block/qcow2.h | 14 ++---
