[resend PATCH 2/2] eventpoll.h: add missing epoll event masks

From: Greg KH
Date: Wed Mar 08 2017 - 13:47:02 EST

[resend due to me forgetting to cc: linux-api the first time around I
posted these back on Feb 23]

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

For some reason these values are not in the uapi header file, so any
libc has to define it themselves. To prevent them from needing to do
this, just have the kernel provide the correct values.
