+ * Name: spin_trylock_irqsave_wo_note

+ * Description:
+ * Try once to lock the spinlock. Do not wait if the spinlock is already
+ * locked.
+ *
+ * This implementation is the same as the above spin_trylock() except that
+ * it does not perform instrumentation logic.
+ *
+ * Input Parameters:
+ * lock - A reference to the spinlock object to lock.
+ * flags - flag of interrupts status
+ *
+ * Returned Value:
+ * SP_LOCKED - Failure, the spinlock was already locked
+ * SP_UNLOCKED - Success, the spinlock was successfully locked
+ *
+ * Assumptions:
+ * Not running at the interrupt level.
