It doesn't. =46ork is only a 'really hot path' if you have a fork bomb running. The=20 scheduler is a really hot path (which Suspend2 patches don't touch, by the= =20 way). The change in the page allocation routine follows a comment saying "This is= =20 the last chance, in general, before the goto nopage." It adds one further=20 test to the four already done at that point.
