Alexei Starovoitov a10423b87a bpf: introduce BPF_MAP_TYPE_PERCPU_ARRAY map ... Primary use case is a histogram array of latency where bpf program computes the latency of block requests or other events and stores histogram of latency into array of 64 elements. All cpus are constantly running, so normal increment is not accurate, bpf_xadd causes cache ping-pong and this per-cpu approach allows fastest collision-free counters.
