If I need to call a function func on a specific CPU which one of the following I should use? 1. smp_rendezvous_cpus(1 << cpuid, ..., func, ...); 2. sched_bind(cpuid); func(); sched_unbind(); Or does it depend on some additional factors? What are the main differences here? And also by extension. If I need to execute func() on all CPUs - which one is better again - smp_rendezvous_cpus() or CPU_FOREACH+sched_bind? Thanks a lot! -- Andriy Gapon
