That's not how the kernel looks like in that case. I'd prefer this as

You have lots of space to indent it to the parenthesis.

Ugh. Somebody really needs to take this code and delete some indent by

Yeah I cam to the same view -- I changed the file to match your
suggestions here and realized that the (many) existing function defs do
not follow your style recommendation. So I mass-changed them and it
came to me I will only annoy the original author by this attempt at
consistency. I started breaking out code into other functions and I
realized I wasn't taking enough care, because it wasn't what I was
trying to achieve, and would have to test it, might introduce bugs and
would be run out of town by a mob with pitchforks.
I deleted the patch and learned to stop getting a tic in my eye every
time a line > 80 cols flys by.
