My sincere apologies. I have trouble with the patch-by-patch
allmodconfig build being very slow on my setup with the headers I'm
touching, and I've been running into false positives with the C=1 &
W=1 checks. I've been trying to look at the nipa scripts and porting
them over to my setup. I'll take a look at the docker image and if
not, at least make sure the patch-by-patch allmodconfig with C=1 and
W=1 is working.
