Ok, that's fine. I can't really do 4.19 right now, someone else will have to take care of that one.

In the meantime, I'll re-send my 4.14 series with just the first two patches, that fix a 4.14-specific backport error.

    I can not take fixes for 4.14 that are not also in 4.19, sorry, as we
    can not have people upgrading to newer kernels and have regressions.
