From: Carlo Caione <[email protected]> For exFAT the file size can be > 4GB. The 'grub_fat_data' is still marking the 'file_size' as grub_ssize_t that is always 32bit when compiling for i386-pc also when using exFAT.
This is causing a problem when trying to open in loopback a > 4GB file from an exFAT partition. Fix this modifying the size of the 'file_size' according to the MODE_EXFAT define.
