Thanks. Yes, I must have been looking at an old version. I guess I’ll have
to use “real” Mutexes. Are they more efficient than spinlocks?

Are you looking at old filemon code (v2.x or earlier)? The latest code
calls KeGetCurrentIrql and queues to a worker thread if at DISPATCH_LEVEL.
Old code did make unsafe calls to ExAcquireFastMutex.
