I'd love to have some feedback specifically about the API. I have also some idea about userspace and how to extend the pmalloc concept to it: http://www.openwall.com/lists/kernel-hardening/2018/01/30/20 I'll be AFK intermittently for about 2 weeks, so i might not be able to reply immediately, but from my perspective this would be just the beginning of a broader hardening of both kernel and userspace that I'd like to pursue. -- igor
