    lib/Kconfig.debug: make TEST_KMOD depend on PAGE_SIZE_LESS_THAN_256KB

    Commit b05fbcc36b ("btrfs: disable build on platforms having page size
    256K") disabled btrfs for configurations that used a 256kB page size.
    However, it did not fully solve the problem because CONFIG_TEST_KMOD
    selects CONFIG_BTRFS, which does not account for the dependency.  This
    results in a Kconfig warning and the failed BUILD_BUG_ON error
    returning.

      WARNING: unmet direct dependencies detected for BTRFS_FS
        Depends on [n]: BLOCK [=y] && !PPC_256K_PAGES && !PAGE_SIZE_256KB [=y]
        Selected by [m]:
        - TEST_KMOD [=m] && RUNTIME_TESTING_MENU [=y] && m && MODULES [=y] && NETDEVICES [=y] && NET_CORE [=y] && INET [=y] && BLOCK [=y]

    To resolve this, add CONFIG_PAGE_SIZE_LESS_THAN_256KB as a dependency of
    CONFIG_TEST_KMOD so there is no more invalid configuration or build
    errors.
