I will try, but I’m not sure. I don’t have a deep enough understanding to resolve some of the conflicts. In my previous mail I wasn’t sure which change would be the right one:

I guess if 6.12 doesn’t have this line at all:

-               atomic_set(&sh->count, 1);

… then setting it to 0 is fine?

+               atomic_set(&sh→count, 0);

But again, I have no idea what’s actually going on there … ;)

If you want I can try to wade through and give you a list of questions where the patch doesn’t obviously apply and you can let me know …

Christian
