kselftest-merge misses config's to merge

Hi,

I have a question about the config files in tools/testing/selftests/ .
The kselftest-merge target in the root Makefile assumes that the
config files are placed in
tools/testing/selftests/*/config and selftests/android/ion/config and
selftests/net/forwarding/config doesn't follow that. So either we move
those files up a level or do something like below in the top Makefile.

 # ---------------------------------------------------------------------------


or do you have another way to solve this?

Cheers,
Anders

I will be happy to add it to the documentation in
Documentation/dev-tools/kselftest.rst with what we say if it
is needed.

Let's move them up to where they need to be and document it as well.

Sorry for the late reply. I was out on vacation all of last week.

thanks,
