From: Johannes Weiner <hannes@xxxxxxxxxxx>
Subject: mm: vmpressure: fix scan window after SWAP_CLUSTER_MAX increase
mm-increase-swap_cluster_max-to-batch-tlb-flushes.patch changed
SWAP_CLUSTER_MAX from 32 pages to 256 pages, inadvertantly switching the
scan window for vmpressure detection from 2MB to 16MB. Fix.
