Thanks you picked a bit of information up from my source code analysis
for a possible adjustment of the function “exfat_rename_file”.

exfat: Improving exception handling in two functions

Would you like to adjust the implementation of the function “exfat_move_file”
in a similar way in a subsequent patch variant?

Regards,
