From b60d17603df3225d9f51c4f8168e8e00a1090911 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd@arndb.de> Date: Wed, 3 Apr 2013 17:14:32 +0200 Subject: [PATCH] sysfs: fix crash_notes_size build warning
commit eca4549f57 "sysfs: Add crash_notes_size to export percpu note size" adds a printk that outputs a size_t value as %lu when it should be %zu, resulting in this warning.
drivers/base/cpu.c: In function 'show_crash_notes_size': drivers/base/cpu.c:142:2: warning: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'unsigned int' [-Wformat=]
