+ * Name: rspin_trylock/rspin_trylock_irqsave/rspin_trylock_irqsave_nopreempt
+ *
+ * Description:
+ *   Nest supported spinlock, try once to lock the rspinlock, can support
+ *   UINT16_MAX max depth.
+ *   As we should not disable irq for long time, sched also locked.
+ *   Similar feature with enter_critical_section, but isolate by instance.
+ *
+ *   If SPINLOCK is enabled:
+ *     Will take spinlock each cpu first call.
+ *
+ *   If SPINLOCK is not enabled:
+ *     Equivalent to up_irq_save() + sched_lock().
+ *     Will only sched_lock once when first called.
+ *
+ * Input Parameters:
+ *   lock - Caller specific rspinlock_s. not NULL.
+ *
+ * Returned Value:
+ *   true  - Success, the spinlock was successfully locked
+ *   false - Failure, the spinlock was already locked
