From 013110a73dcf970cb28c5b0a79f9eee577ea6aa2 Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Tue, 8 Sep 2015 15:04:10 -0700 Subject: mm/page_alloc.c: fix a misleading comment The comment says that the per-cpu batchsize and zone watermarks are determined by present_pages which is definitely wrong, they are both calculated from managed_pages. Fix it.
