Re: CONFIG_SMALL_KERNEL option added

[MFLD <mfld.fr@gmail.com>]

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
