The current calling conventions for ->follow_link() are already fairly complex. What we have is 1) you can return -error; then you must release nameidata yourself and ->put_link() will _not_ be called. 2) you can do nd_set_link(nd, ERR_PTR(-error)) and return 0 3) you can do nd_set_link(nd, path) and return 0 4) you can return 0 (after having moved nameidata yourself) jffs2 follow_link() is broken - it has an exit where it returns -EIO and leaks nameidata.
