I'm seeing the same thing after clear upgrade 2.14 to master (currently 2.15):

lustre-MDT0000: clear the changelog for cl1 of all records
lustre-MDT0000: Deregistered changelog user #1

UPD. Apparently, in my case the problem was using mds for SINGLEMDS, instead of mds1. With mds1 the 160* set of changelog_user sanity tests worked fine.
