The problem with the lockdep issues that are plaguing the CI is they
only appear every now and then. So we would only notice after applying,
when the amount of noise reduces. I would use the above as a reference
that the patch will not make things worse.

You can take a look at /archive/results/CI_IGT_test/bsw-nuc-2.html to
see for yourself a long-term history.
