This still seems to be in the mmotm tree http://www.ozlabs.org/~akpm/mmotm/broken-out/mm-add-additional-consistency-check.patch I hope we have agreed that this is not the right approach to handle invalid pointers in kfree and rather go soemthing like http://lkml.kernel.org/r/20170411141956.gp6...@dhcp22.suse.cz instead. -- Michal Hocko SUSE Labs
