That looks horrible and it causes a checkpatch warning.  :(  Why not
do it the same way that everyone else does it.

	if (blah_blah_x && <-- && has to be on the first line for checkpatch
	    blah_blah_y) { <-- [tab][space][space][space][space]blah

Now all the conditions are aligned visually which makes it readable.
They aren't aligned with the indent block so it's easy to tell the
inside from the if condition.

I kind of hate all this extra documentation because now everyone thinks
they can invent new hoops to jump through.

Speaking of hoops, the BPF documentation says that you have to figure
out which tree a patch applies to instead of just working against
linux-next.  Is there an automated way to do that?  I looked through my
inbox and there are a bunch of patches marked as going through the
bpf-next tree but about half were marked incorrectly so it looks like
everyone who tries to tag their patches is going to do it badly anyway.
