IIRC it hasn't. Not in upstream anyway. Some distros (e.g. opensuse) carry their own patch which allows cross-subvolume links (cp --reflink ...). But it shouldn't matter anyway, since you can SNAPSHOT the old subvol (even root subvol), instead of creating a new subvol. Which means nothing needs to be copied. You'd still have to do "rm" manually though. -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
