In the Linux kernel, the following vulnerability has been resolved:
ext4: check stripe size compatibility on remount as well
We disable stripe size in _ext4fillsuper if it is not a multiple of the cluster ratio however this check is missed when trying to remount. This can leave us with cases where stripe < clusterratio after remount:set making EXT4B2C(sbi->sstripe) become 0 that can cause some unforeseen bugs like divide by 0.
Fix that by adding the check in remount path as well.
