From: Linus Torvalds on 12 Apr 2010 16:50 From: Linus Torvalds <torvalds(a)linux-foundation.org> Date: Sun, 11 Apr 2010 17:15:03 -0700 Subject: [PATCH 3/4] anon_vma: clone the anon_vma chain in the right order We want to walk the chain in reverse order when cloning it, so that the order of the result chain will be the same as the order in the source chain. When we add entries to the chain, they go at the head of the chain, so we want to add the source head last.
