4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Williams <[email protected]> commit af7d9f0c57941b465043681cb5c3410f7f3f1a41 upstream. Fix the format specifier so that the attribute can be parsed correctly. Currently it returns decimal 1000 for a 4096-byte alignment.
