Are there any issues with ExTryToAcquireFastMutex. Should I include
hal.lib to resolve it, or is there a better dll. Every time I’ve tried it,
gives me a weird fault that looks like the implib address is bogus.

Another option is to use a spin lock instead of a fast mutex. You should
only do this if you are holding the lock for short periods of time.

Queue the IRP instead if your resource is busy, and pick it later.
