Adding "--param allow-store-data-races=0" to the GCC options for the kernel breaks C=1 because Sparse isn't expecting a GCC option with that format.
It thinks allow-store-data-races=0 is the name of the file we are trying to test. Try use Sparse on linux-next to see the problem. $ make C=2 mm/slab_common.o CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CALL scripts/checksyscalls.sh CHECK scripts/mod/empty.c No such file: allow-store-data-races=0 make[2]: *** [scripts/mod/empty.o] Error 1 make[1]: *** [scripts/mod] Error 2 make: *** [scripts] Error 2 $ regards, dan carpenter
