The reasoning looks valid to me. Neil, commit cd045e31 contains -u16 tcpu = map->cpus[((u32) (skb->rxhash * map->len)) >> 16]; +tcpu = map->cpus[((u64) skb->rxhash * map->len) >> 32]; Could you confirm this is just an overlook? Thanks! Jiri, yes, thats correct, Due to ABI contraints we have to shift by 16 instead of 32 and cast to a u32 *** This bug has been marked as a duplicate of bug 757040 *** |
