We're thinking about using TAINT_USER to indicate when a user has installed a Ksplice update that they generated on their own. We'd like to be able to distinguish between the cases (1) where a user has generated a potentially-bad Ksplice update by providing their own naughty patch and (2) where a user is running binary Ksplice updates provided by a vendor that is taking care to use Ksplice properly. Our patch currently uses TAINT_KSPLICE to indicate whether _any_ Ksplice update has been applied. -Tim Abbott -- 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/
