Hm... No. I get a second warning:
kernel/trace/trace_events_filter.c:2052 ftrace_profile_set_filter()
error: uninitialized symbol 'filter'.
kernel/trace/trace_events_filter.c
2036
2037 err = -EEXIST;
2038 if (event->filter)
2039 goto out_unlock;
2040
2041 err = create_filter(call, filter_str, false, &filter);
2042 if (err)
2043 goto free_filter;
^^^^^^^^^^^
filter is uninitialized. What are we supposed to be freeing?
2044
2045 if (ftrace_event_is_function(call))
2046 err = ftrace_function_set_filter(event, filter);
2047 else
2048 event->filter = filter;
2049
2050 free_filter:
2051 if (err || ftrace_event_is_function(call))
2052 __free_filter(filter);
2053
2054 out_unlock:
2055 mutex_unlock(&event_mutex);
2056
2057 return err;
2058 }
