From 2feeaf8433c8e68de3d0a06a0ffe7742bcd13c1a Mon Sep 17 00:00:00 2001 From: David Howells Date: Sat, 20 Oct 2018 00:57:59 +0100 Subject: afs: Eliminate the address pointer from the address list cursor 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.
