Because they are human? I certainly forgot similar details when writing code, 
numerous times, and making constructs more robust against mistakes is half of
my job as a maintainer. This is kernel design 101.

WTF? Really, I've given you useful feedback in the last couple of days, and my 
suggestions were generally correct and on topic, still your replies were 
passive-aggressive, obtuse and generally foul tempered in every single case.

Just the latest example:

I made a routine, technically valid suggestion that I made countless other
kernel developers in the past who sent me code with such a pattern, and
I do not appreciate your condescending tone, it's not about 'making me happy'.

You need to handle criticism of your patches properly and constructively.
