3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Peter Hurley <[email protected]> commit e1082f45f1e2bbf6e25f6b614fc6616ebf709d19 upstream. If the src msg is > 4k, then dest->next points to the next allocated segment; resetting it just prior to dereferencing is bad.
