newbie SMP question

I have been trying to understand some basic SMP stuff( not specific to freebsd). I have a few real basic questions about OS support for SMP.Just to clarify- does the kernel run as various threads on each processor? Is the kernel stack the only non-shared entity among the various threads? I would a

Re: sk_buff on FreeBSD
