This matches the anon_vma_clone() case, and uses the same lock helper functions. Because of the need to potentially release the anon_vma's, it's a bit more complex, though. We traverse the 'vma->anon_vma_chain' in two phases: the first loop gets the anon_vma lock (with the helper function that only takes the lock once for the whole loop), and removes any entries that don't need any more processing. The second phase just traverses the remaining list entries (without holding the anon_vma lock), and does any actual freeing of the anon_vma's that is required.
