There are three bugs in this code:
1) If indx_get_root() fails, then return -EINVAL instead of success.
2) On the "/* make root external */" -EOPNOTSUPP; error path it should
free "re" but it has a memory leak.
3) If indx_new() fails then it will lead to an error pointer dereference
when we call put_indx_node().
I've re-written the error handling to be more clear.
