Well, is there any missing patch related to exfat_find()? It would be nice to modify the caller of this function, exfat_find(), so that this change in functionality doesn't affect other functions. Thanks.
Whoops, it's a bug. I didn't catch that, thanks. Maybe it could make exfat inode hash problem. I wanted to reuse current function interface but, it would be better to add an addtional parameter. I'll fix this in v2.
