    Subject[PATCH] Do not __always_inline bvec_kmap_irq() and bvec_kunmap_irq()

    So remove both the comment and the inline requirement, going back to the
    inline hint.

    So I came up with this, but I'm not sure if it's better than just avoid the

    patch, let me know.

    Thanks a lot,
