3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Sasha Levin <[email protected]> commit 6b8d9117ccb4f81b1244aafa7bc70ef8fa45fc49 upstream. The timeout entries are sizeof(int) rather than sizeof(long), which means that when they were getting read we'd also leak kernel memory to userspace along with the timeout values.
