From d0bb1f42f4f28df5f463e283b8bf4de18f73d357 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Wed, 26 Sep 2012 11:34:01 +1000 Subject: [PATCH] mm: remove unevictable_pgs_mlockfreed Simply remove UNEVICTABLE_MLOCKFREED and unevictable_pgs_mlockfreed line from /proc/vmstat: Johannes and Mel point out that it was very unlikely to have been used by any tool, and of course we can restore it easily enough if that turns out to be wrong.
