It doesn't explain it at all. In fact I don't see why we neeed three attempts, just do the GFP_NOFAIL as the second and final step.
Second attempt is reduced size only as we don't want to GFP_NOFAIL if we can avoid it helping the allocator. We go from an arbitrary allocation to the smallest possible allocation, if all that fails ok lets use GFP_NOFAIL. I don't know how this is not clear...
