Thanks for your patch, which is now commit 120b116208a08772
("maple_tree: reorganize testing to restore module testing")
in v6.1-rc5.

    +config TEST_MAPLE_TREE
    +       select DEBUG_MAPLE_TREE
    +       tristate "Test the Maple Tree code at runtime"
    +

There are two problems with this:

  1. If CONFIG_DEBUG_KERNEL=n:

        WARNING: unmet direct dependencies detected for DEBUG_MAPLE_TREE
          Depends on [n]: DEBUG_KERNEL [=n]
          Selected by [m]:
          - TEST_MAPLE_TREE [=m] && RUNTIME_TESTING_MENU [=y]

  2. IMHO test code should not silently enable additional features, as
     it prevents providing a test module for a production system,
     without having any other impact on that system.

Thanks!

Gr{oetje,eeting}s,

                        Geert
