This adds the "read-only" option to the QDict. One important effect of this change is that when a child inherits options from its parent, the existing "read-only" mode can be preserved if it was explicitly set previously. This addresses scenarios like this: [E] <- [D] <- [C] <- [B] <- [A] In this case, if we reopen [D] with read-only=off, and later reopen [B], then [D] will not inherit read-only=on from its parent during the bdrv_reopen_queue_child() stage. The BDRV_O_RDWR flag is not removed yet, but its keep in sync with the value of the "read-only" option. Signed-off-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com> |
