3.5.7.29 -stable review patch. If anyone has any objections, please let me know.
------------------ From: "Yan, Zheng" <[email protected]> commit fc55d2c9448b34218ca58733a6f51fbede09575b upstream. We also need to wake up 'safe' waiters if error occurs or request aborted. Otherwise sync(2)/fsync(2) may hang forever.
