From 68f7c82ab1b8c7057b0c241907ff7906c7407e6d Mon Sep 17 00:00:00 2001 From: Binbin Wu Date: Wed, 22 Mar 2023 12:58:24 +0800 Subject: [PATCH] KVM: x86: Change return type of is_long_mode() to bool Change return type of is_long_mode() to bool to avoid implicit cast, as literally every user of is_long_mode() treats its return value as a boolean.
