Clean them up to be what? Shorter? Nice? Full of rounded edges so
that when we bump into them in the dark they don't poke us and cause us
to shreak in pain?

Sweet, you cloned yourself, I thought only Alan Cox had achieved that
goal...

Hey, I was right, it does have more rounded edges, nicely done.

Again with the function return value hiding. Please don't.

I really don't understand this change at all. "obj" is just as vapid
and clueless as "ctx" is, and it seems very gratuitous to change this.
And I should know, I have made a lot of gratuitous renames in my time in
the kernel...

After seeing this stuff so many times I'm waiting for a helper function
to be added for it in this subsystem. I'm sure you really don't want to
edit GUID printk-like functions ever again, right?

I think by virtue of the kfree() right above this comment, it should be
deleted. Especially as it is at the end of the function, making it
pretty much impossible to make any sense here...
Come on, global search-and-replace needs to be done in a sane manner,
other wise you can just send me a vi macro to run on the code, it would
be the same thing in the end (hint, don't do that, only one person has
ever gotten away with doing that in the history of the kernel, in an act
never to be ever repeated again.)
