There've been some other patchsets proposed recently that need to print a 
thread's comm and since /proc/pid/comm can change the comm's of other 
threads out from under them, it's necessary to serialize access to it with 
task_lock().  This patch certainly makes it easier for modules to do so 
correctly, thanks!
