Yes, I think you're right. This requires some changes to the kerneldoc and utrace.tmpl, because it now says that you get EALREADY if report_reap is already running. Now it will be consistent with utrace_control, where you get ESRCH either if report_reap might already be running or if it's entirely detached and/or reaped. Thanks, Roland
