Sorry that I had not yet provided that information. You should have
received this information through another e-mail thread. See also

+AD4 To do that, you have to understand what recursion is valid (I'm guessing
+AD4 there's some sort of layering involved), and I'm far from understanding
+AD4 anything about the code that triggered this report.

I don't think there is any kind of recursion involved in the NVMe code
that triggered the lockdep complaint. Sagi, please correct me if I got this
wrong.
