    test_bpf: reduce MAX_TESTRUNS · 9960d766
    Eric Dumazet authored
    For tests that are using the maximal number of BPF instruction, each
    run takes 20 usec. Looping 10,000 times on them totals 200 ms, which
    is bad when the loop is not preemptible.
    
    test_bpf: #264 BPF_MAXINSNS: Call heavy transformations jited:1 19248
    18548 PASS
    test_bpf: #269 BPF_MAXINSNS: ld_abs+get_processor_id jited:1 20896 PASS
    
    Lets divide by ten the number of iterations, so that max latency is
    20ms. We could use need_resched() to break the loop earlier if we
    believe 20 ms is too much.
