Return value
Returns TRUE if the caller should lower IRQL to below DISPATCH_LEVEL.
Remarks
When this function returns TRUE:
- If the caller is running in thread context (i.e. not in an interrupt or DPC), it should lower IRQL to below DISPATCH_LEVEL.
- If the caller is within a DPC or cannot directly lower IRQL, it should queue work to a worker thread and return.
