Mark Johnston 8ff6d9dd22 Support an arbitrary number of arguments to DTrace syscall probes. ... Rather than pushing all eight possible arguments into dtrace_probe()'s stack frame, make the syscall_args struct for the current syscall available via the current thread. Using a custom getargval method for the systrace provider, this allows any syscall argument to be fetched, even in kernels that have modified the maximum number of system call arguments.
