We then keep in net->ipvs a pointer to some freed memory. Commit 14e405461e664b7 did some changes in this area Simon, any idea ? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
