Getting epoll working...?

[Alan Kasindorf]

Also, I fixed the other headers already. It's the mystery of epoll.h 
that's been bugging me.

Getting a binary would probably be helpful for just seeing if I've even 
patched the kernel right at this point. Would much appreciate it!

Note that this is a .... redhat 7.2 machine.... I might be able to get 
8.0 on it if it ends up being required, but likely nothing newer.
