SubjectRe: [PATCH v5 13/14] epoll: implement epoll_create2() syscall

Instead of adding a new syscall, is setting size (and/or even
the EPOLL_USEREPOLL flag) something that could be done via
ioctl?

There's no race like CLOEXEC to worry about and it's not
going to be in a hot path where the extra syscall matters.

glibc won't need to increase in .so size, either.
