[-- Type: text/plain, Size: 2123 bytes --]

3.6.11.3 stable review patch.
If anyone has any objections, please let me know.

------------------

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

[ Upstream commit 7f49ef69db6bbf756c0abca7e9b65b32e999eec8 ]

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.
