When new permissions are calculated during bdrv_reopen(), they need to be based on the state of the graph as it will be after the reopen has completed, not on the current state of the involved nodes. This patch makes bdrv_is_writable() optionally accept a BlockReopenQueue from which the new flags are taken. This is then used for determining the new bs->file permissions of format drivers as soon as we add the code to actually pass a non-NULL reopen queue to the .bdrv_child_perm callbacks. While moving bdrv_is_writable(), make it static. It isn't used outside block.c. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> |
