FAT is Microsoft's filesystem and the only usage of it on Linux is due
to interoperability with different non-Linux systems. So here we should
implement FAT in the similar/same way as other systems. It does not make
sense to implement it differently and specially in non-compatible way.
Because it lost reason what is primary usage of the FAT on Linux.
