From 757265b8c57bb8fd91785d3d1a87fb483c86c9c2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 28 Feb 2008 20:19:06 +0100 Subject: [PATCH] x86: delay the export removal of init_mm delay the removal of this symbol export by one more kernel release, giving external modules such as VirtualBox a chance to stop using it.
