The function kstrtoul() used to parse number strings in the mount option parser is set to expect a base 10 number . This treats the octal numbers passed for mount options such as file_mode as base10 numbers leading to incorrect behavior.
Change the 'base' argument passed to kstrtoul from 10 to 0 to allow it to auto-detect the base of the number passed.
