If it is "kinda like a mini function" why not make it "actually a mini function" and 
call it?

I really don't like the indenting here.  When I first glanced over that code I 
thought "case FOO:", "case error:", "case BAR:".  Only later after reading your 
description did I realize error wasn't part of the switch, but an independent label.

It hurts my eyes.  Not that I'm the coding style czar or anything, if I were the 
kernel coding style would be different in several ways.  But inasmuch as this is a 
democracy (which it isn't) then I am opposed to crazy indentation such as your example.
