From: Jan Kara Date: Fri, 10 Feb 2017 05:56:09 +0000 (-0500) Subject: ext4: do not use stripe_width if it is not set X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5469d7c3087ecaf760f54b447f11af6061b7c897;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ext4: do not use stripe_width if it is not set Avoid using stripe_width for sbi->s_stripe value if it is not actually set. It prevents using the stride for sbi->s_stripe.
