Nice series. > On another note, I'm still not sure whether I should leave all of this work > enabled for 1.5, or if we wouldn't be better off with disabling it for the > release so that we have some additional months before we commit to the > interface. Any opinions? I suggest we leave this series and the io_flush series I sent recently out of QEMU 1.5. Once they are reviewed, let's merge them into block-next. When 1.6 opens they'll be the first things to get merged. Unless there's an urgent need to get this into 1.5, I don't see the big win - QMP changes are still missing anyway. Let's not rush it. Also, I guess documentation changes are missing to really make this feature ready for end-users :). Stefan
