Sadly, the point is that EXPERIMENTAL is enabled in all distros and by most users, so you *could* flag your feature CONFIG_EXPERIMENTAL, but the only thing taht might accomplish is making you feel ok to be less careful. Of course, an alternative to this patch would be a purging - pull the CONFIG_EXPERIMENTAL tag from all options which anyone might be wanting to use by default. Then let CONFIG_EXPERIMENTAL serve its original purpose. -serge -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
