Thanks for the helpful report, I love the new feature of grabbing the patches
from the list.

Moreover, sorry for screwing up here, I changed the function name before
sending it out and only compiled the files individually but did not notice
that I only changed it in three out of four places because I did not
try to relink the kernel.

I'll send an updated version.
