/* * Destroy a selinfo record. The owning object must not gain new * references while this is in progress: all activity on the record * must be stopped. * * Concurrency issues: we only need guard against a call to selclear() * by a thread exiting sel_do_scan(). The caller has prevented further * references being made to the selinfo record via selrecord(), and it * will not call selnotify() again. */
