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. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=13058 Reported-and-tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Rafael J.
