So you'll have to be more specific about the scenario you are describing.

If there's a user thread that is still running the proc_*_dma()
function, and we agree that this thread keeps running until completion
and then returns to user space, what's the problem ?

If that user thread will crash, drv_remove_all_resources() will clean
up all map_obj's.

I wouldn't worry about that.. In the worst case, "Cc:
stable@xxxxxxxxxx" will push the fix into 2.6.37.x..
