If we fail to make the procfs structure here, we just report and carry on. The rest of the kernel can function without it, so failure isn't critical. But I should make this clear in the comments. There is no real error handling required, but we can clarify that with comments. I'll try to address this in a coming patch.

Part of the reason for error handling is just to silence static checker
warnings because otherwise everyone has to review it to see if the
resource leaks are important.  It's easier in the long run to just fix
everything no matter how trivial.
