According to the reporter it works on Debian which is still running a
4.19 kernel
My guess is that it worked before
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=538af88ea7d9de241e6b6f006e9049c4d96723bb
as the error was ignored
And I believe it would have worked again until
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5bedd3afee8eb01ccd256f0cd2cc0fa6f841417a
as a waorkaround was added at some point (it changed at
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fb314eb0cbb2e11540d1ae1a7b28346397f621ef
but was laready there)
