Christoph and/or Jeff, I updated the patch for 3.18-rc1 and I'm going to resend it as non-RFC as I didn't get comments last time. I only have one stupid question... I'm going to rename the calls to preadv6 and pwritev6 (so it's more like the other syscalls: dup3, accept4, eventfd2) but I'm not sure if i should call it preadv5 or pwritev6 since the offset argument is split into two different arguments (upper and lower part). Also, In our application we were able to get about 20%-30% reduction in response time when using this before queuing in a IO thread pool on the read path. It's a pretty nice win in the real world.
