Detecting kprobes generated code addresses

Hi Masami,

I would like to make __kernel_text_address() be able to detect whether
an address belongs to code which was generated by kprobes. As far as I
can tell, that information seems to be in the 'pages' lists of
kprobe_insn_slots and kprobe_optinsn_slots. But they seem to be
protected by mutexes. Do you know if there's a sleep-free way to access
that information?
