I did run checkpatch, it didn't say a word about this.

What is your recommendation about typedef'ining a function pointer?
I immediately suspected that using a callback function might sound like 
heresy, so if you have any better suggestion please put it forward 
before I rework this changeset for the fifth time... please.

I just think having the whole, expanded signature as the type for a 
function-pointer parameter or local variable would just make things too 
long and redundant.
Just off the top of my head: perhaps a struct with a single function 
pointer element might look better than a typedef?

Thanks,
