I've read the discussions around the change and from the user's POV I'd suggest to add another mount option that would be just an alias for any mount options that would implement the 'hard-ro' semantics. Say it's called 'nowr'. Now it would imply 'nologreplay', but may cover more options in the future. mount -o ro,nowr /dev/sdx /mnt would work when switching kernels. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
