That's a quite reasonable request, but I'm really surprised by it at this point. The proposed ABI is one very straightforward extension to one existing system call, plus four others that you personally suggested. They haven't *changed* since last November: http://lkml.iu.edu/hypermail/linux/kernel/1511.2/00985.html I see you added Mel and Hugh to the cc. Is that who you'd like to see review it? Is there anyone else? I'd expect Mel and Hugh's review time to be highly contended, and I'd rather not gate these on them. If it helps anyone review these more easily, I've html-ized the affected manpages and published them: https://www.sr71.net/~dave/intel/manpages/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
