From 63b23e2cbc8e80de3e40184ecb2c3bfb705776fa Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 10 Jul 2017 15:51:20 -0700 Subject: [PATCH] kernel/kallsyms.c: replace all_var with IS_ENABLED(CONFIG_KALLSYMS_ALL) 'all_var' looks like a variable, but is actually a macro. Use IS_ENABLED(CONFIG_KALLSYMS_ALL) for clarification.
