If you can't understand why a buffer overflow is bad then I honestly
don't know what to say...

When I was a newbie, I encountered a driver which was written in
terrible style.  And I thought why do people allow it???  This is
garbage and it's messing up the Linux kernel with its bad style.

But after I got older, I realized that he was the only person with that
hardware and the only person who cared about it.   If I started fighting
with him about style then he would leave.  He was a quirky guy with bad
taste but he was still making useful contributions so it was better to
tolerate him.

These days I'm the old quirky guy.  If you want to fight with me about
commit messages, that's fine.  I can easily just add you to my list of
subsystems which only receive bug reports instead of patches.  (I think
only BPF is on the list currently because it's annoying to track the
bpf vs bpf-next tree).

Feel free to re-write this patch however you want and give me
Reported-by credit.
