Excerpt from man epoll_create:
"If flags is 0, then, other than the fact that the obsolete flags argument is dropped, epoll_create1() is the same as epoll_create()."
Actually, it's the obsolete *size* argument that's dropped, not the obsolete *flags* argument. Also, the comma after "then" should be dropped.
the comma is correct
ive sent the flags->size typo upstream
