    If I understand it correctly, this patch fixes a backwards compat bug in
    code introduced 2 patches earlier:
    [PATCH 08/10] drbd: Introduce protocol version 100 headers

    Therefore this patch (and its commit message) should just be rolled into
    that one to prevent the bug in the first place.

    Cheers,
