From 5d946c5abbaf68083fa6a41824dd79e1f06286d8 Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Wed, 20 Nov 2019 01:10:42 +0100 Subject: xsk: Fix xsk_poll()'s return type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit xsk_poll() is defined as returning 'unsigned int' but the .poll method is declared as returning '__poll_t', a bitwise type. Fix this by using the proper return type and using the EPOLL constants instead of the POLL ones, as required for __poll_t.
