Once enabled it does stay on, and strictly speaking it does change the disk format. But, it is perfectly safe to go back to a non-space_cache enabled kernel and then go back into space cache. Josef set things up so it would detect a non-space_cache mount and continue properly. space_cache is wonderful. We did fix up a few bugs in .38 and .39 but I'll probably have .40 enable it by default. -chris -- 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
