Description

I was just looking at some crashes happening on my testbed and noticed some very weird stuff in there that looks like we are trying to do something very incorrect on cleanup.

The issue seems to have been there for a while unnoticed, but we should dig to find out what's going on I think.

This happens on lustre cleanup or client eviction all the time for me basically, no matter the test.
