Prove to me that there's an issue here beyond theoretical analysis, then I'll consider that patch. Show me a compiler used to compile the kernel that zeros out the increment. Show me were the race actually occurs. I think the READ/WRITE_ONCE() is more confusing than helpful. And unneeded churn to the code. And really not needed for something that's not critical to execution. -- Steve
