Hi Greg, here's another one. When you have a chance can you please apply commit c0eb027e5aef ("vfs: don't do RCU lookup of empty pathnames") to the stable trees? I can reproduce the use-after-free on 4.4-stable and 4.9-stable, and it is fixed by the patch. And I wasn't able to check 3.18 because KASAN isn't available there, but I think the bug there as well. Thanks,

Thanks for this, I'll queue it up for the next round of stable patches after this one.
