Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ext4: check stripe size compatibility on remount as well<br /> <br /> We disable stripe size in __ext4_fill_super if it is not a multiple of<br /> the cluster ratio however this check is missed when trying to remount.<br /> This can leave us with cases where stripe s_stripe) become 0 that can cause some<br /> unforeseen bugs like divide by 0.<br /> <br /> Fix that by adding the check in remount path as well.
