Thanks to everyone that responded!! My resolution is to wait_event_interruptible where I check the condition when I am awaken. If the condition is equal to the condition that I set elsewhere when I get what I am waiting for, then I handle the data and return it to the user. If the condition is not what I expect, then I know that it was a signal that caused me to continue. At that point, I simply return from my blocking I/O and assume that if the user app is still running it will ask again or if has crashed, then the module can be unloaded if need be.
