Hugh Dickins 2e441889c3 swapoff: scan ptes preemptibly ... Provided that CONFIG_HIGHPTE is not set, unuse_pte_range can reduce latency in swapoff by scanning the page table preemptibly: so long as unuse_pte is careful to recheck that entry under pte lock. (To tell the truth, this patch was not inspired by any cries for lower latency here: rather, this restructuring permits a future memory controller patch to allocate with GFP_KERNEL in unuse_pte, where before it could not. But it would be wrong to tuck this change away inside a memcgroup patch.)
