Hello Steven Rostedt,
Commit e6187007d6c3 ("tracing/events: add startup tests for events")
from Apr 15, 2009 (linux-next), leads to the following Smatch static
checker warning:
kernel/trace/trace_events.c:4704 event_test_stuff()
error: 'test_thread' dereferencing possible ERR_PTR()
kernel/trace/trace_events.c
4698 static __init void event_test_stuff(void)
4699 {
4700 struct task_struct *test_thread;
4701
4702 test_thread = kthread_run(event_test_thread, NULL,
"test-events");
4703 msleep(1);
--> 4704 kthread_stop(test_thread);
Check for if (!IS_ERR(test_thread)) ?
4705 }
regards,
dan carpenter
