Hi, I'm trying to understand memory barriers but not quite succeeding. Consider the following example: Start: p = NULL; x = 0; CPU1: atomic_inc(&x); p = &x; CPU2: if (p) z = atomic_read(p); Is it possible to end up with z == 0? What if there's a lock/unlock before setting "p"? What if there's a write barrier before setting "p"?
