3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Chris Mason <[email protected]> commit 7d78874273463a784759916fc3e0b4e2eb141c70 upstream. We need to NULL the cached_state after freeing it, otherwise we might free it again if find_delalloc_range doesn't find anything.
