Just for information, you don't need the three lines above. There are ony
useful when you want the semantic patch to support several kinds of
output.
Ok, I think I added them from copying a coccicheck script, and if I
delete virtual patch I get
"virtual rule patch not supported"
when running:
make coccicheck COCCI=sg_phys.cocci MODE=patch
I suspect I am invoking it wrong.
