Yes, I was thinking of the exact same thing after seeing the bot's error
message. I just did not yet find some time to test.

The kernel test robot actually gives instructions on how to reproduce, but for
some reasons which I have not yet troubleshot, it did not work on first try on
my machine.

Well, you know what, because we reached the same conclusion, allow me to be a
bit lazy here. I will just send the v2 and let the bot test it for me.


Yours sincerely,
