Edward Adam Davis 6921d1e07c tracing: Fix filter logic error ... If the processing of the tr->events loop fails, the filter that has been added to filter_head will be released twice in free_filter_list(&head->rcu) and __free_filter(filter). After adding the filter of tr->events, add the filter to the filter_head process to avoid triggering uaf.
