    The caps lock interface. As I said, caps lock is caps lock, it's not
    shift lock. For now Linux uses caps lock. If you make it use shift
    lock it completely changes the behavior.

    Yes, that's shift lock. But then any other key will also be shifted,
    not only the KT_LETTER ones, while it's exactly the purpose of KT_LETTER
    and caps lock.

    It seems we don't understand each other, I'll repeat what I have
    understood and explain more:

    - you say
    > Note: patch relies on keymap being consistent wrt SMALL/CAPITAL symbols.

    - I understand
    patch relies that keymaps always have the capital variant of letters at
    the shifted position of each keys.

    - I answer
    > And that's not true for a lot of keyboard symbols.

    - I mean
    Some keyboard (physical, bought at the local store, not just keymaps
    from CrazyHacker) do _not_ always have the capital variant of letters at
    the shifted position of each keys. On a french keyboard for instance, É
    is not at shift+é, but altgr+shift+é. So your patch won't work and
    actually do harm.

    - You answer
    > That's why patch implies keymap is not fucked up.

    - I understand
    That's why patch implies that french keyboard is not fucked up.

    - I answer
    > However you can't changed the "fucked up" keyboard of people. They have
    > bought it and it's printed like that on it...

    - I mean
    Maybe it's fucked up, but all the french keyboards are like that, you
    can't change that fact.

    - You answer
    > keymap is loadable, what are you talking about?
    > /usr/share/keymaps/i386/qwerty/ru.map.gz

    - I didn't understand anything.
