Subject: [ 23/27] ftrace: Move ftrace_filter_lseek out of CONFIG_DYNAMIC_FTRACE section
Date: Sun, 14 Apr 2013 19:43:22 -0700 [thread overview]
Message-ID: <20130415024233.069872762@linuxfoundation.org> (raw)
In-Reply-To: <20130415024231.351969241@linuxfoundation.org>
3.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>
commit 7f49ef69db6bbf756c0abca7e9b65b32e999eec8 upstream.
As ftrace_filter_lseek is now used with ftrace_pid_fops, it needs to
be moved out of the #ifdef CONFIG_DYNAMIC_FTRACE section as the
ftrace_pid_fops is defined when DYNAMIC_FTRACE is not.
