I'm sorry for the belated reply.
Right, quite similar, but not exactly, I believe. I deliberately wanted to untangle vcpu preemption (which is a characteristics feature) from pv-lock, which may be somewhat implementation dependent.
Perhaps vcpu_is_preempted() should not even be implemented on per-arch basis, but instead it can be more of a "core" functionality.
