So that commit is expected to fix things, but it also *enabled* the selftests to warn about the change.
Did you run the new selftest on an old kernel?
It looks that way, because you talk about running the selftests for commit 8bb2610bc496 (which is 4.17-rc2+), but the dmesg you include is some ancient version"
Linux version 4.12.0-10998-g6974f0c
Hmm. Some of those self-tests are very much expected to break on old kernels.
