Arg, I didn't know that you could export just a part of the selftest
tree. Thanks for the report.

I'm traveling for a few days. I'll look into how to fix the inclusion
problem when I get back on October 19th.

In the meantime, if you just want to run the bonding tests you can do:

(in tree)
make -C tools/testing/selftests run_tests TARGETS="drivers/net/bonding"

or

(exported)
make -C tools/testing/selftests gen_tar
[... extract archive ...]
./run_kselftest.sh -c drivers/net/bonding


It seems like a plausible fix might be to use symlinks, what do you
think?
