2023-11-08block: Protect bs->file with graph_lockKevin Wolf
Almost all functions that access bs->file already take the graph lock now. Add locking to the remaining users and finally annotate the struct field itself as protected by the graph lock.

2023-09-21parallels: collect bitmap of used clusters at openDenis V. Lunev
If the operation is failed, we need to check image consistency if the problem is not about memory allocation. Bitmap adjustments in allocate_cluster are not performed yet. They worth to be separate. This was proven useful during debug of this series. Kept as is for future bissecting. It should be specifically noted that used bitmap must be recalculated if data_off has been fixed during image consistency check. Signed-off-by: Denis V.

We are going to use it in more places, calculating "s->tracks << BDRV_SECTOR_BITS" doesn't look good.
