Peter Zijlstra b3e0b1b6d8 locking, sched: Introduce smp_cond_acquire() and use it ... Introduce smp_cond_acquire() which combines a control dependency and a read barrier to form acquire semantics. This primitive has two benefits: - it documents control dependencies, - its typically cheaper than using smp_load_acquire() in a loop.
