For v5.2 and later (including upstream) please send a patch to simply replace get_cpu() with smp_processor_id(). The reason is that get_cpu() will not disable BH and according to the call path this function is invoked in NAPI callback and the other sides does local_bh_disable(). Therefore the caller of this must ensure that BH is disabled and disabling preemption is not enough. Sebastian
