[PATCH 1/3] get_utrace_lock() must not succeed if utrace->reap == T

[Roland McGrath]

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
