For 4.5, I'd like to address the send queue accounting and invalidation/unmap ordering issues Jason brought up a couple of months ago. In preparation for Doug's final topic branch, Anna, I've rebased these on Christoph's ib_device_attr branch, but there were no merge conflicts or other changes needed. Could you begin preparing these for linux-next and other final testing and review?
