Subject: [PATCH] mm/rmap: correct obsolete comment of page_get_anon_vma()
Since commit 746b18d421da ("mm: use refcounts for page_lock_anon_vma()"),
page_lock_anon_vma() is renamed to page_get_anon_vma() and converted to
return a refcount increased anon_vma. But it forgot to change the
relevant comment.
