>Description:
POLL_ERR and POLL_HUP  are defined in <sys/signal.h>, they both have the same value (4). I doubt whether it is deliberate or not. It looks more like a typo.
The same value causes problems for "case POLL_ERR:", "case POLL_HUP:" handling.

It doesn't look like kernel generates these codes so far.

>How-To-Repeat:

>Fix:
#define POLL_HUP      6       /* Device disconnected                  */
