- * Name: sched_removereadytorun
- *
- * Description:
- * This function removes a TCB from the ready to run list.
- *
- * Inputs:
- * rtcb - Points to the TCB that is ready-to-run
- *
- * Return Value:
- * true if the currently active task (the head of the
- * g_readytorun list) has changed.
- *
- * Assumptions:
- * - The caller has established a critical section before calling this
- * function (calling sched_lock() first is NOT a good idea -- use irqsave()).
- * - The caller handles the condition that occurs if the
- * the head of the g_readytorun list is changed.
