"I'll stop making predictions about whether this is the last pull request for 2.6.26 or not, but it is an important one. It turns out that we've had a trivial DoS on machines containing PCI devices with bad VPDs. We're entertaining a few options for a scalable, long term fix, but in the meantime, restricting access to the sysfs VPD file seems prudent. I've included the patch in lieu of a diffstat since it's so small."
