Debug for #23913, I though if we have no idea which process is nuking
the volume then we need to figure this out. As there is no reproducer
we can (ab)use the cleanup tracer. Simply trace all unlink syscalls to
see which process deletes our special named volume. Given the volume
name is used as path on the fs and is deleted on volume rm we should
know exactly which process deleted it the next time hopefully.
