Yes:

http://marc.info/?l=linux-kernel&m=139523745403081&w=2

The following cases are tested:

1) plain rename (flags = 0)
2) cross rename
3) noreplace rename

For each the following are tested:

a) same directory rename
b) cross directory rename

And all combinations of source and dest being:

- negative
- regular file
- symlink
- empty dir
- nonempty dir

After the operation the file type of both source and dest are checked
(or the error value returned).

Thanks,
Miklos
