Subject: ftrace: Remove unused unregister_ftrace_function_probe_all() function
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=78f78e07d51e440d01e6b1aef172883821193771;p=openwrt%2Fstaging%2Fblogic.git

ftrace: Remove unused unregister_ftrace_function_probe_all() function

There are no users of unregister_ftrace_function_probe_all(). The only probe
function that is used is unregister_ftrace_function_probe_func(). Rename the
internal static function __unregister_ftrace_function_probe() to
unregister_ftrace_function_probe_func() and make it global.

Also remove the PROBE_TEST_FUNC as it would be always set.
