From a21e25536169432cf9174d631972bc1cd4c75062 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sat, 18 Apr 2009 17:23:41 +0200 Subject: [PATCH] PM/Hibernate: Fix memory shrinking Commit d979677c4c0 ("mm: shrink_all_memory(): use sc.nr_reclaimed") broke the memory shrinking used by hibernation, becuse it did not update shrink_all_zones() in accordance with the other changes it made. Fix this by making shrink_all_zones() update sc->nr_reclaimed instead of overwriting its value.
