    Quoting Eric Biggers <ebiggers@kernel.org>

    I don't expect any problem with backporting this, but I don't see how
    this
    follows the stable kernel rules
    (Documentation/process/stable-kernel-rules.rst).
    I don't see what distinguishes this patch from ones that don't get
    picked up by
    AUTOSEL; it seems pretty arbitrary to me.

    - Eric

    And I agree, this should not be in stable.

    Best regards,
    Pavel
