From 287d97ac032136724143cde8d5964b414d562ee3 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 10 Apr 2010 15:22:30 -0700 Subject: [PATCH] vma_adjust: fix the copying of anon_vma chains When we move the boundaries between two vma's due to things like mprotect, we need to make sure that the anon_vma of the pages that got moved from one vma to another gets properly copied around. And that was not always the case, in this rather hard-to-follow code sequence. Clarify the code, and fix it so that it copies the anon_vma from the right source.
