Andrew,

I think this was missed in the patch fix up we emailed about.  You added
a fix to drop this line in "mm-drop-oom-code-from-exit_mmap-fix" but
that fix should be for "mm: remove the vma linked list".  This was a
merge conflict since this line was added between my v9 and the
re-addition of the maple tree.

Thanks,
Liam
