4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jan Kara <jack@xxxxxxx> [ Upstream commit 5469d7c3087ecaf760f54b447f11af6061b7c897 ] Avoid using stripe_width for sbi->s_stripe value if it is not actually set. It prevents using the stride for sbi->s_stripe.
