But I still plan to send out the pull request very soon, maybe today (ouch, it's already 12:30). I wanted to include the record-replay patches, but they are big enough that they probably deserve their own pull request, and my queue already has 23 patches... > Please let us know is something from our side will improve the > situation. No, it's just my issue. However, there is something we can improve about the process. QEMU typically updates header files around 4.3-rc5 (by importing the changes destined to 4.4), so we need a place to put this kind of patch that depends on Linux header changes. Therefore: 1) I've made a staging branch uq/hyperv (uq = upstream queue) on git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git - you can base your patches on that branch as soon as I create it. 2) if you have more changes to asm/hyperv.h, bundle them and send them to kvm@vger.kernel.org. I'll include them in kvm/queue all at the same time, which will make header file synchronization less of a problem in the future. Paolo
