Function _dfs_normalize_path

components/dfs/dfs_v2/src/dfs_file.c:160–179

* @brief Normalize a path by combining base path and link path * * This function creates a temporary path by combining the base path and link path, * then normalizes it using dfs_normalize_path(). It handles memory allocation and * cleanup internally. * * @param[in] path The base path to combine with the link * @param[in] path_len Length of the base path * @param[in] link_fn The link path

 * @note The caller is responsible for freeing the returned path
