So those fixes aren't going in, so "the swap storms would be fixed" argument isn't actually an argument at all as far as 5.3 is concerned. End result: we'd have the qemu-kvm instance performance problem in 5.3 that apparently causes distros to apply those patches that you want to revert anyway. So reverting would just make distros not use 5.3 in that form. So I don't think we can revert those again without applying the two patches in the series. So it would be a 5.4 merge window operation.
