From ca0488aadd014809862428cde896a6a6e8f13e42 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Fri, 15 Mar 2019 18:58:15 +0100 Subject: [PATCH] kvm: don't redefine flags as something else MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The function irqfd_wakeup() has flags defined as __poll_t and then it has additional flags which is used for irqflags. Redefine the inner flags variable as iflags so it does not shadow the outer flags.
