Hi,
I run this command:
make allmodconfig ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-
make C=2 drivers/vdpa/vdpa_sim/vdpa_sim_net.o ARCH=x86_64
CROSS_COMPILE=x86_64-linux-gnu-
Yeah, I can see the warning using C=2.
I'll use it next times.
Thanks for sharing,
Stefano

I built with W=1 but I didn't have this warning.
Thanks for fixing,
