Subject: [PATCH] tools/testing: add kselftest shell helper library
From: Willem de Bruijn <willemb@...gle.com>
Kselftest expects processes to signal pass/fail/skip through exitcode.
C programs can include kselftest.h for readable definitions.
Add analogous kselftest.sh for shell tests. Extract the existing
definitions from udpgso_bench.sh.
Tested: make TARGETS=net kselftest
Link: https://patchwork.kernel.org/project/netdevbpf/patch/20201113231655.139948-4-acardace@redhat.com/
Signed-off-by: Willem de Bruijn <willemb@...gle.com>

applies cleanly to netnext (f9e425e99b07) and kselftest (v5.10-rc1)
