Comment 1 for bug 1828597

This is really a bug on the kernel, after and including 4.18.

This is due to a patch that we have been carrying since forever, and when the involved code changed a lot from 4.15 to 4.18, the patch was dropped, as it couldn't be easily fixed up.

Even before that happened, I tried to upstream the patch, resending it to the mailing list, but PPC maintainers wanted something different. The original author resent with some modifications, but maintainers wouldn't still apply it. As far as I remember, that patchset doesn't apply anymore after the referred changes.

I have tried to work on a different solution, considering the new code base, but didn't have much time to get a working solution.

Cascardo.
