Hi everyone, I'm now playing net-next samples/bpf things, and I found that test_maps will give an assertion
``` test_maps: /home/grd/linux/net-next/samples/bpf/test_maps.c:146: test_percpu_hashmap_sanity: Assertion `bpf_lookup_elem(map_fd, &key, value) == -1 && errno == ENOENT' failed. [1] 20706 abort (core dumped) ./test_maps ``` I've done the check at [[iovisor-dev] Assertion fails at samples/bpf/test_maps](http://lists.iovisor.org/pipermail/iovisor-dev/2016-June/000281.html) which tells me to set ulimit to unlimited or patching by setrlimit(). The problem is bpf_lookup_elem return -1, and errno return 0. I'm using Intel(R) Core(TM) i7-2640M and net-next commit: 803783849fed11, 4.8.0-rc7-ARCH-02283-g8037838. And, a strange this is when I done this at QEMU, test_maps perform will and pass the test. Is that my hardware problem or something else? Thanks. Louie Lu.
