    Subject[PATCH v3 2/2] selftests: bpf: test_kmod.sh: use modprobe on target device
    Date
    From: Naresh Kamboju <naresh.kamboju@linaro.org>

    On ARM and ARM64 devices kernel source tree is not available so
    insmod "$SRC_TREE/lib/test_bpf.ko" is not working.

    On these target devices the test_bpf.ko is installed under
    /lib/modules/`uname -r`/kernel/lib/
    so use modprobe dry run to check for missing test_bpf.ko module and
    insert for testing.
