- * rte_make_tmp_attrs - prepare route by adding all relevant temporary route attributes
- * @r: route entry to be modified (may be replaced if COW)
- * @lp: linpool from which to allocate attributes
- * @old_attrs: temporary ref to old &rta (may be NULL)
- *
- * This function expands privately stored protocol-dependent route attributes
- * to a uniform &eattr / &ea_list representation. It is essentially a wrapper
- * around protocol make_tmp_attrs() hook, which does some additional work like
- * ensuring that route @r is writable.
- *
- * The route @r may be read-only (with %REF_COW flag), in that case rw copy is
- * obtained by rte_cow() and @r is replaced. If @rte is originally rw, it may be
- * directly modified (and it is never copied).
- *
- * If the @old_attrs ptr is supplied, the function obtains another reference of
- * old cached &rta, that is necessary in some cases (see rte_cow_rta() for
- * details). It is freed by rte_store_tmp_attrs(), or manually by rta_free().
- *
- * Generally, if caller ensures that @r is read-only (e.g. in route export) then
- * it may ignore @old_attrs (and set it to NULL), but must handle replacement of
- * @r. If caller ensures that @r is writable (e.g. in route import) then it may
- * ignore replacement of @r, but it must handle @old_attrs.
