selftests/bpf: Add tests for cgrp_local_storage with local percpu kptr

Browse source

Add a non-sleepable cgrp_local_storage test with percpu kptr. The
test does allocation of percpu data, assigning values to percpu
data and retrieval of percpu data. The de-allocation of percpu
data is done when the map is freed.
