STOP submitting this crap, NOW!

I told you I won't review nor apply these patches any more.

And ever worse, this one is BUGGY.

We're testing p->fp so we know if we can safely dereference
it or not.

You're adding an OOPS to the kernel.

This is why these mindless mechanical transformations are not
only often a waste of time, they are dangerous as well.

I am silently rejecting from patchwork, immediately, any and all
patches you submit of this nature.
