Hello Jody,
Reducing the kernel size by making it less verbous looks fine, but I
think the option is misnamed and that could lead to confusion. A newbie
like me would understand that option as "reduce the kernel features to
gain space", not the amount of traces. So I would rename it something
like "VERBOSE_LESS" ?
Also, could it be possible to make such changes like this latest one in
another development branch, so that we could have a stable master
branch, as the official Linux, so that we could review, test, validate
and mature the changes on our different platforms before merging them ?
Regards,
Marc-F. Lucca-Daniau
