So we'd have a comprehensive, 100% coverage, self-sufficient set of callbacks
that
track the kernel's current context state at the points where the context
switches
actually occur - not just something cobbled together heterogenously. The low
level
x86 asm code was rather messy in this area, better organization would be
welcome,
I don't think we can overdo it.
( I'm assuming here that it can all be done for zero or negative cost, and that
the result will be correct and won't hurt existing users in any fashion. )
Thanks,
Ingo
