3.16.7-ckt20 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Mike Snitzer <[email protected]> commit 4dcb8b57df3593dcb20481d9d6cf79d1dc1534be upstream. btree_split_beneath()'s error path had an outstanding FIXME that speaks directly to the potential for _not_ cleaning up a previously allocated bufio-backed block. Fix this by releasing the previously allocated bufio block using unlock_block().
