From 5dc4ac6324094cd52dc77ddf88296a94b90bbafc Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Sun, 15 Jul 2007 23:38:23 -0700 Subject: [PATCH] mspec_mmap: don't set VM_LOCKED mspec_mmap was setting VM_LOCKED (without adjusting locked_vm): don't do that, it serves no purpose in 2.6, other than to mess up the locked_vm accounting - mspec's pages won't get reclaimed anyway. Thanks to Dmitry Monakhov for raising the issue.
