1 \subsection{026: use a refcount on each SA to increase locking granularity}
3 \subsubsection{026: Definition of requirement }
5 Each SA object will use reference counts to determine when it may be freed.
7 The SAs will be referenced from eroute's via an indirection table, reducing
8 the need to search by SAID, yet not introducing new pointers that may not be
9 easy to find. This same index will occur in {\tt skb->nfmark} references.
