Gcc doesn't believe in your guarantee. Are you sure gcc doesn't? Or is it just "C"? Linux wouldn't work today if gcc did something non-atomic there (presuming you're talking about naturally aligned pointers/ints). It is widely used and accepted. RCU users are far from the only places to rely on this, although I guess they are the main ones when it comes to assigning pointers atomically. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
