2015-05-12nvmap: page pool: fix background threadColin Cross
Fix a race condition in the background allocator where wake_up_process could be called just before set_current_state changed the state to TASK_INTERRUPTIBLE, causing the thread not to wake. Use a waitqueue instead. Also make the background allocator nicer by marking it freezable so it doesn't compete with suspend, and setting it SCHED_IDLE so it only runs when no other threads want to run.
