Oh, I see. The problem being not that we can get the buffer on the wrong list but that we can wander into the wrong list ourselves... Ho-hummm... Methink your solution is wrong, though. Better one: do non-blocking scan of the lists, gathering the stuff that should die into the separate (local) list. while the list is non-empty pick the first buffer, wait_on_buffer move it to free list. Comments? I'm more worried about the loop device handling...
