I didn't get to read the patch throughly yet but I am really confused by this statement. The api is mprotect based which makes it ineherently PAGE_SIZE granular. How do you want to achieve cache line granularity with this API? And I would really vote for simplicity first... Subpage granularity sounds way too tricky... -- Michal Hocko SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
