Since get_pid_task() grabs a reference on the task_struct, we have to drop the refcount after reading that task's comm name. Use pid_task() with RCU instead. Also, avoid directly reading like pid_task()->comm because pid_task() will return NULL if the task have already exit()ed. This patch fixes both problems.
