Subject: [for-next][PATCH 06/25] tracing: Make ftrace_trace_stack() static
Date: Thu, 01 Oct 2015 07:55:30 -0400 [thread overview]
Message-ID: <20151001115636.897696674@goodmis.org> (raw)
In-Reply-To: <20151001115524.066462793@goodmis.org>
[-- Attachment #1: 0006-tracing-Make-ftrace_trace_stack-static.patch --]
[-- Type: text/plain, Size: 2280 bytes --]
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
ftrace_trace_stack() is not called outside of trace.c. Make it a static
function.
