I hadn't heard from Andrew in a while so I'm not 100% clear on whether his patches had fixed the race that he had spotted in the NFSv4 unhashing code. Still, once he had done the analysis, the problem was clear. I think this patchset should fix the problem in a relatively clean way. I've run some tests against this and it seems to not have broken anything, but I haven't been able to reproduce the actual race so I can't verify that this fixes it. Andrew, Anna, if you are able to do so could you test these patches and let us know whether this fixes those races?
