Subject[PATCH 23/25] afs: Eliminate the address pointer from the address list cursor [ver #2]
From
Date
Eliminate the address pointer from the address list cursor as it's
redundant (ac->addrs[ac->index] can be used to find the same address) and
address lists must be replaced rather than being rearranged, so is of
limited value.
