Ahh, great, thx for letting me know.

Thanks to a proper Link tag regzbot would have noticed that fix once it
landed in next, but it's nevertheless good to know that the fix is
already under review. :-D

Fun fact: sometimes I wish we would not post fixes in new threads, as
that makes it hard to find the proposed fix for anybody that runs into
reported issues and also manages to find the report (e.g. this thread).
But whatever, that's just a detail.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
