4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Nicolas Iooss <[email protected]> commit 31b239824ece321c09bdb8e61e1d14814eaba38b upstream. The word "background" contains 10 characters so the third argument of strncmp() need to be 10 in order to match this prefix correctly.
