----
Test case: fs/vfs/t_vnops/udf_dir_notempty

Duration: 0.920299 seconds
Termination reason

FAILED: non-empty directory removed succesfully
Standard output stream


Test case: fs/vfs/t_vnops/udf_dir_rmdirdotdot

Duration: 0.912503 seconds
Termination reason

FAILED:
/tmp/bracket/build/2013.07.02.22.39.45-amd64/src/tests/fs/vfs/t_vnops.c:181:
Expected errno 2, got 22, in rump_sys_chdir("..") == -1

>How-To-Repeat:
Run the tests
        
>Fix:
The rmdir '..' case ought to be trivial to fix, the other needs some
attention. It turns out that the reference count udf is using there is only
counting references TO the directory and not, as abusively is presumed, the
number of files too.
