We need a 6.4 version of the fix to get rid of the regression. If you
want to do cleanups on top of that, then that's fine and that can go into
6.5. But don't mix them up.
Hmm, it seems nothing has happened here since ten days to fix this
regression that likely is still present in 6.3. Yu Kuai, did it fall
through the cracks, or is what Jens asked for more complicated than it
sounds?
Sorry for the delay, I was waiting for the last patch to be reviewed.
But the regression is only related to the first patch, I'll send it
seperately.
Thanks,
Kuai
Or was progress made and I just missed it?
