I realize and appreciate that I'm not supposed to nag you folks for feedback. But I don't know how to proceed. So, rather than nag you, I've filed a bug: https://bugzilla.kernel.org/show_bug.cgi?id=115031 I've tested my patch; I believe it to be the simplest change that resolves this bug. I'm happy to write something else if it would be cleaner and/or help others, but I would need a more-detailed explanation of what you're looking for. I've also filed a ticket downstream: Red Hat appears to not build the ipddp module with their stock kernel release, so their users don't hit this bug. But Ubuntu does build/ship ipddp; if they likewise didn't, that would also solve my problem: https://bugs.launchpad.net/ubuntu/+source/linux-lts-wily/+bug/1559772 Adam
