That doesn't look like the safest approach to me. Somehow I felt more comfortable with exception_enter/exit on the audit function. A few other archs use schedule_user() as well, it's likely fine but I'm not sure how subtle their path is. Besides, is it possible that the audit function gets called after syscall_trace_leave() or do_notify_resume()? If so, the patch won't fix the issue entirely. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
