Steve, Follow a series to handle multiple ip addresses per hostame when mounting, chasing DFS referrals and reconnecting. We've defined a maximum number of 16 addresses a hostname can handle as we did in mount.cifs (resolve_host.c::resolve_host). If that's not OK, then we could make it flexible by creating a new mount option like 'maxaddrs=N' or just increase it in both sides. The mount.cifs(8) patch that passes multiple 'ip=' options to handle all resolved addresses will be posted soon.
