    Subject[PATCH 4.4 23/40] ext4: do not use stripe_width if it is not set
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    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.
