Hi Benjamin

As pointed out by others, this breaks ABI. It can be very hard to
change anything in include/uapi/linux without some user space code
breaking. Also, the use case of case-insensitive filesystem is not
particularly relevant today, how many are the in active use now? There
might be a stronger argument for case magic filesystems, but i would
argue the magic is broken, which is not really Linux's problem.
