Subject: [RFC PATCH for-next 2/4] epoll: epoll() syscall declaration
Date: Sun, 23 Feb 2014 17:42:40 -0800
Message-ID: <> (raw)
In-Reply-To: <>

Add prototype for epoll() system call, defined in fs/eventpoll.c. This
interface behaves like kevent() in BSD systems in that it supports
the addition/deletion/modification of eventpoll entries in the same
system call that polls for ready events.
