A newbie= =20 like me would understand that option as "reduce the kernel features to=20 gain space", not the amount of traces. So I would rename it something=20 like "VERBOSE_LESS" ? Also, could it be possible to make such changes like this latest one in= =20 another development branch, so that we could have a stable master=20 branch, as the official Linux, so that we could review, test, validate=20 and mature the changes on our different platforms before merging them ?
