From 8befedfe678ff84d5bc356be4f3cb1fd84959d02 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Mon, 8 Oct 2012 16:33:42 -0700 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.
