The test script works when kernel source and build module test_bpf.ko
present on the machine. This patch will check if module is present in
the path.

Looks good, what changed between v1 and v2? Didn't get the cover
letter in case there was one. ;)

Which tree are you targeting? There are usually a lot of changes
in BPF selftests going the usual route via net and net-next tree
as we often require to put test cases along the BPF patches. Given
the merge window now and given one can regard it as a fix, it's
net tree. I'm also ok if Shuah wants to pick it up this window as
test_kmod.sh hasn't been changed in quite a while, so no merge
conflicts expected.

Anyway, for the patch:

Acked-by: Daniel Borkmann <daniel@xxxxxxxxxxxxx>

Thanks!
