Subject[PATCH review for 3.18 04/12] ext4: do not use stripe_width if it is not set
Date
From: Jan Kara <jack@suse.cz>

[ 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.
