The stress test's WARN_ON_ONCE(!sktp->tp) check in the child thread is racy and unnecessary: since kthread_run() wakes the thread before returning, the child can run before sktp[i].tp has been assigned. Moreover, sktp->tp is never actually used in the child function, so the check serves no purpose. Remove it and keep the original kthread_run() Also add a common cleanup path for thread creation failures. If creating one of the later threads fails, stop all threads that were already started and free the allocated array instead of leaving orphan kthreads and leaked memory behind. Finally, replace the module-static doneflag with kthread_should_stop(). With the doneflag, child threads may exit before the parent calls kthread_stop(), so the task lifetime is no longer guaranteed when the parent later tries to stop them. Using kthread_should_stop() keeps each child alive until kthread_stop() synchronously terminates it.
