Peter, you mentioned https://lkml.org/lkml/2020/8/10/439 patch to distinguish real writes vs enforced COW read requests, however I also see that you had a later version of this patch here: https://lore.kernel.org/patchwork/patch/1286506/. Which one should I backport? Or is it not needed in the absence of uffd-wp support in the earlier kernels?

Sorry I have no ability to evaluate the rest... but according to Linus's previous reply, my understanding is that it is not needed, not to mention it's not upstreamed too.

Thanks,
