So I have just looked again and I don't see anything. There are a couple of subtle issues on x86. Especially with saving floating point but as I read the code copy_thread initializes things properly so that code that doesn't touch floating point registers doesn't need to do anything. The important thing for lurking issues is that even if I missed something practically all of the uses of PF_KTHREAD are on x86 or generic code so they should be flushed out quickly. Eric
