It turns out this is a longstanding bug in 4.19.y and 4.14.y caused by a bad
backport, which is not actually related to the above commit (or the patch series
that contained it) at all. I've sent out fixes:
4.19: https://lore.kernel.org/r/20230317062743.313169-1-ebiggers@kernel.org
4.14: https://lore.kernel.org/r/20230317062801.313217-1-ebiggers@kernel.org
