I like how this patch illustrates how easy it is to use the new method for 
printing a task's command, but it would probably be easier to get the 
first two patches in the series (those that add the seqlock and then %ptc) 
merged in mainline and then break out a series of conversions such as this 
that could go through the individual maintainer's trees.
