I might have missed something, but it seems nothing has happened since a
week. Sure, this is hardly a new regression, so it's not that urgent;
still it would be good to see this fixed rather sooner than later after
all the publicity this got. So allow me to quickly ask:

Is anyone (Christoph?) already working on such a patch or is it at least
somewhat high on somebody's todo list?

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