- * Here's a sample kernel module showing the use of jprobes to dump
- * the arguments of _do_fork().
- *
- * For more information on theory of operation of jprobes, see
- * Documentation/kprobes.txt
- *
- * Build and insert the kernel module as done in the kprobe example.
- * You will see the trace data in /var/log/messages and on the
- * console whenever _do_fork() is invoked to create a new process.
- * (Some messages may be suppressed if syslogd is configured to
- * eliminate duplicate messages.)
