Hi Shuah,

First, thank you for maintaining the Kernel Selftest framework!

Commit 852c8cbf34d3 (selftests/kselftest/runner.sh: Add 45 second
timeout per test) adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.

- tools/testing/selftests/rtc (rtc) is OK,
- tools/testing/selftests/net/mptcp (net/mptcp) is not.

We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:

tools/testing/selftests/*/*/**/Makefile

Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.

ok 1 selftests: net/mptcp: mptcp_connect.sh

Before we had:

ok 1 selftests: mptcp: mptcp_connect.sh

But showing the full target name is probably better, just in case a
subsubdir has the same name as another one in another subdirectory.

Sorry to bother you again with this but by chance, did you have a look at the patch below? :)

It doesn't only fix an issue with MPTCP, not in the kernel yet. But it also fixes the issue of taking the right "settings" file (if available) for any other tests in a sub-directory, e.g.:

drivers/dma-buf
filesystems/binderfs
net/forwarding
networking/timestamping

But I guess all tests in powerpc/* dirs and others.

Cheers,
Matt
