They should and it would be great to see that. Unfortunately this
isn't he case. Some examples (from 4.15):
test_kmod.sh - path to the module is wrong
https://lkml.org/lkml/2017/11/6/654

sync - missing cflags in makefile
https://patchwork.kernel.org/patch/10166499/

seccomp_bpf - open(2) is a legacy syscall, replaced with openat(2) since 2.6.16
https://lkml.org/lkml/2018/1/9/1141

reuseport_bpf: this test doesn't give consistent results. It usually
fails when ran from run_kselftests.sh script. Passes when run
standalone on 1st attempt and fails again on 2nd attempt.

There is also a group of tests (BPF) that are not correctly built in
our openembedded build. The OE recipe needs to be fixed to make sure
all .o files are where they are expected to be. There are more failed
tests, but I don't have a good explanation what is going on.

These are usually old problems and they are also included in the
skiplist for mainline. We're trying to report any regressions in
mainline tests, but this work has slightly lower priority than LTS :(
