- * Name: sched_garbagecollection
- *
- * Description:
- *   Clean-up memory de-allocations that we queued because they could not
- *   be freed in that execution context (for example, if the memory was freed
- *   from an interrupt handler).
- *
- *   This logic may be called from the worker thread (see work_thread.c).
- *   If, however, CONFIG_SCHED_WORKQUEUE is not defined, then this logic will
- *   be called from the IDLE thread.  It is less optimal for the garbage
- *   collection to be called from the IDLE thread because it runs at a very
- *   low priority and could cause false memory out conditions.
- *
- * Input parameters:
- *   None
- *
- * Returned Value:
- *   None
- *
