I suspect the real culprit is commit a4f91f0de905 ("of: unittest: clean up changeset test"), or at least it changes the code enough for the offending patch not to work in v4.14.y and older. Either case, reverting upstream commit b3fb36ed694b ("of: unittest: kmemleak on changeset destroy") fixes the problem and thus needs to be dropped from v4.4.y, v4.9.y, and v4.14.y.
