Without space_cache (once), btrfs has to repopulate that information the slow way every mount; with it, it can just load the data from the last unmount (modulo some consistency checks). The setting is sticky, so you don't actually need it in fstab any more (although it won't hurt anything either). -- 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
