I've submitted it to my linux-next branch for testing, and the upstream commit is well tested, but would also appreciate any testing that folks would be kind enough to provide. I'm sending this to you, Linus, to make sure that you're aware of my intent to send you this hot fix. I intend to let it bake in linux-next for a day or two, and get some community testing, then send you a pull request with this change. Please let me know if there is anything else I should do, or if there is a different process that I should be following.
