Subject: [PATCH v3 0/3] proper locking on bitmap add/remove paths
Date: Fri, 20 Sep 2019 11:25:40 +0300 [thread overview]
Message-ID: <20190920082543.23444-1-vsementsov@virtuozzo.com> (raw)
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
block/qcow2.h | 14 ++---
include/block/block_int.h | 14 ++---
include/block/dirty-bitmap.h | 5 +-
block.c | 22 -------
block/dirty-bitmap.c | 119 +++++++++++++++++++++++++++++++++--
block/qcow2-bitmap.c | 36 +++++++----
block/qcow2.c | 5 +-
blockdev.c | 28 +++------
