- Prevent that the allocation path wakes up kswapd. That's a long
standing issue due to the GFP_ATOMIC allocation flag. As debug objects
can be invoked from pretty much any context waking kswapd can end up
in arbitrary lock chains versus the waitqueue lock.
- Correct the explicit lockdep wait-type violation in
debug_object_fill_pool().
