I definitly agree that ino/dev pair should be a unique identity on the system. But I don't know why you are tryng to solve the problem in generic VFS layer instead of the problematic FS. Isn't it an unnecessary overhead for many FS? How about creating a new f_op member ->get_ino_dev(), ->show_identity() or something, and implement the new f_op in the problematic FS only? I hope it will be a lighter way to get the pair than generic getattr way. J. R.
