- Initialize 'ret' local variables on fprobe_handler() to fix the smatch
warning. With this, fprobe function exit handler is not working
randomly.
- Fix to use preempt_enable/disable_notrace for rethook handler to
prevent recursive call of fprobe exit handler (which is based on
rethook)
- Fix recursive call issue on fprobe_kprobe_handler().
- Fix to detect recursive call on fprobe_exit_handler().
- Fix to make all arch-dependent rethook code notrace.
(the arch-independent code is already notrace)
