Maybe Joakim can remove it. The non irq-safe spin_lock was there before my patch and now it is removed with the #if 0/#endif block. I don't need this code but I left it there disabled to make it clear for everyone else that it was removed. I can remove it but I rather leave it there for one release so everyone will have a chance to see it and object if they feel differently. > = > (By the way, I'd feel safer about this patch if there were an > ack or two from more PPC folk...) Yeah, that would be good. Jocke
