I will discuss the current status of kernel SMP
support, the rthreads thread library, and relevant
future developments. Over the years, we have
accumulated several concurrency primitives in the
kernel, causing some confusion amongst developers,
so I will lay out the origin and correct usage for
each. The talk is primarily targeted at the budding
OpenBSD kernel developer, but I will also describe
the end-user effects of each topic.
