From f17845e5d97ead8fbdadfd40039e058ec7cf4a42 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 24 Oct 2008 12:47:10 +0200 Subject: ftrace: warning in kernel/trace/ftrace.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit this warning: kernel/trace/ftrace.c:189: warning: ‘frozen_record_count’ defined but not used triggers because frozen_record_count is only used in the KCONFIG_MARKERS case. Move the variable it there. Alas, this frozen-record facility seems to have little use. The frozen_record_count variable is not used by anything, nor the flags. So this section might need a bit of dead-code-removal care as well.
