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 https://lore.kernel.org/linux-fsdevel/208cba7b-e535-c8e0-5ac7-f15170117a7f@xxxxxx/ https://lkml.org/lkml/2020/6/10/272 Would you like to adjust the implementation of the function “exfat_move_file” in a similar way in a subsequent patch variant?
