Question About ev_epoll.c:_do_fork()

[Kazuhiro Takenaka]

Hello

I am reading ev_epoll.c:_do_fork() of HAProxy-1.8.30.

In its comment, the following sentence appears.

  If it fails, it disables the poller by setting
  its pref to 0.

But I can't find out such code in _do_fork();

I also read _do_fork() of HAProxy-2.4.0 and its
comment doesn't have the above sentence.

Also, There is no difference between code of
_do_fork() of 1.8.30 and that of 2.4.0 except
REGPRM1 declaration.

So I thought the above sentense would be
unnecessary to HAProxy-1.8.30.

Is my thought correct?
