Subject: [PATCH 1/2] selftests: bpf: test_kmod.sh: check if module is present in the path before insert

From: Naresh Kamboju <naresh.kamboju@...aro.org>

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.
