What's the current status of this series?
We had some iterations of patches, but the only solution that works for me is the patch with the coarse-grained lock that I sent at Mon, 08 Sep 2014 10:16:48 CEST [1] Viresh is pretty occupied lately, but he told me that he might do the tests himself when the current period of busyness is over as he is supplied with a test system. I'm not sure about his current status (busy or testing).
