From a0c5e813f087dffc0d9b173d2e7d3328b1482fd5 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Mon, 8 Oct 2012 16:33:21 -0700 Subject: mm: remove free_page_mlock We should not be seeing non-0 unevictable_pgs_mlockfreed any longer. So remove free_page_mlock() from the page freeing paths: __PG_MLOCKED is already in PAGE_FLAGS_CHECK_AT_FREE, so free_pages_check() will now be checking it, reporting "BUG: Bad page state" if it's ever found set. Comment UNEVICTABLE_MLOCKFREED and unevictable_pgs_mlockfreed always 0.
