250 | * Z90QUIESCE (not recommended) | ||
251 | * Quiesce the driver. This is intended to stop all new | ||
252 | * requests from being processed. Its use is NOT recommended, | ||
253 | * except in circumstances where there is no other way to stop | ||
254 | * callers from accessing the driver. Its original use was to | ||
255 | * allow the driver to be "drained" of work in preparation for | ||

257 | * | ||
258 | * NOTE: once issued, this ban on new work cannot be undone | ||
259 | * except by unloading and reloading the driver. | ||
