Jens doesn't want the kiocb to grow beyond a single cacheline, and we
want the ability to set the loff_t in userspace for an appending write,
so the plan was to replace the ki_complete member in kiocb with an
loff_t __user *ki_posp.

I don't think it's worth worrying about growing kiocb, personally,
but this seemed like the easiest way to make room for a new pointer.
