Duh, so essentially it tells you that you have a non-static function
that lacks a previously defined prototype, but because it's
non-static, it's likely used elsewhere and the prototype might get
out of sync with the actual function definition?
I guess it's no big deal to include the ptlrpc_internal.h there
to catch potential problems like that.
Thanks.
