[30/83] ftrace: Move ftrace_filter_lseek out of CONFIG_DYNAMIC_FTRACEsection

[Ben Hutchings]

3.2.47-rc1 review patch.  If anyone has any objections, please let me know.

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

From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

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.

Cc: Namhyung Kim <namhyung@xxxxxxxxxx>

[bwh: Backported to 3.2:
 - ftrace_filter_lseek() is static and not declared in ftrace.h
 - 'whence' parameter was called 'origin']
