* Since xchg() doesn't always do that, it would seem that following defintion
* is incorrect. But here's the rationale:
* SMP : Even xchg() takes the atomic_ops_lock, so OK.
- * LLSC: atomic_ops_lock are not relevent at all (even if SMP, since LLSC
+ * LLSC: atomic_ops_lock are not relevant at all (even if SMP, since LLSC
* is natively "SMP safe", no serialization required).
* UP : other atomics disable IRQ, so no way a difft ctxt atomic_xchg()
* could clobber them. atomic_xchg() itself would be 1 insn, so it
