#     Pull probes fixes from Masami Hiramatsu:
#      "Fix possible use-after-free issue on kprobe registration.
#     
#       check_kprobe_address_safe() uses `is_module_text_address()` and
#       `__module_text_address()` separately.
#     
#       As a result, if the probed address is in a module that is being
#       unloaded, the first `is_module_text_address()` might return true but
#       then the `__module_text_address()` call might return NULL if the
#       module has been unloaded between the two.
#     
#       The result is that kprobe believes the probe is on the kernel text,
#       and skips getting a module reference. In this case, when it arms a
#       breakpoint on the probe address, it may cause a use-after-free.
#     
#       To fix this issue, only use `__module_text_address()` once and get a
#       reference to the module then. If it fails, reject the probe"
