Hi, In March I reported that a randconfig build complained: ERROR: modpost: missing MODULE_LICENSE() in drivers/iio/afe/iio-rescale.o (https://lore.kernel.org/all/16509fb6-e40c-e31b-2c80-264c44b0beb9@xxxxxxxxxxxxx/) I am still seeing this problem so I tried to dig into it a bit. However, I don't see why get_next_modinfo() and friends don't find the MODULE_LICENSE() since it is in the iio-rescale.o file. (BTW, I see this build error on many different $ARCH [around 15 tested] and with 2 different versions of GCC.) Q1: Is modpost checking both vmlinux and iio-rescale.o for modinfo license strings? It looks like it is, because it appears (?) that modpost is looking at drivers/iio/test/iio-test-rescale.o (<<<<< a kunit test, which is builtin in my .config) and at drivers/iio/afe/iio-rescale.o (which is built as a loadable module). Is this confusing modpost? I renamed drivers/iio/afe/iio-rescale.c to afe-rescale.c and changed its Makefile entry accordingly and the MODULE_LICENSE error goes away. Is this a modpost error or is kunit messing things up? thanks for looking. -- ~Randy
