v3: - add CONFIG_LSM_ENABLE and refactor resulting logicKees, you can add my Reviewed-by:Casey Schaufler [off-list ref] for this entire patch set. Thank you for taking this on, it's a significant and important chunk of the LSM infrastructure update.Thanks! John, you'd looked at this a bit too -- do the results line up with your expectations? Any thoughts from SELinux, TOMOYO, or IMA folks?
What's it relative to? First patch fails for me on current security/next. Is there a branch in your repo that has the v3 patches?
