Miklos, I'm wondering what the status here is. The description in the reverts André sent[1] are maybe a bit vague[2], but it sounds a lot like he ran into a big regression that should be addressed somehow -- maybe with a revert. But it seems we haven't got any closer to that in all those ~7 weeks since the first revert was posted. But I might be missing something, hence a quick evaluation from your side would help me a lot here to understand the situation.
I don't think the Android use case counts as a regression.
If they'd use an unmodified upstream kernel, it would be a different case.
But they modify the kernel heavily, and AFAICS this breakage is related to such a modification (as pointed out by Bernd upthread).
André might want to clarify, but I've not seen any concrete real world examples of regressions caused by this change outside of Android.
Thanks, Miklos
