From 5e9b397292ca0b9409dced33e3a22ec993377064 Mon Sep 17 00:00:00 2001 From: Li Zefan Date: Mon, 2 Nov 2009 08:51:13 +0800 Subject: [PATCH] tracing: Fix to use __always_unused attribute ____ftrace_check_##name() is used for compile-time check on F_printk() only, so it should be marked as __unused instead of __used.
