Tue 09 Jan 2018 08:20:12 PM UTC, comment #4: So should we probably initialize the zone instead of adding a function to compare zone-less? |

Mon 08 Jan 2018 09:36:47 PM UTC, comment #3: The ip6_addr_assign_zone() function is used to set zones, and it only does it for addresses with certain scope. It is therefore safe to compare both the address and zone in all cases.

Nevermind. I've added a comment to say why ip_addr_cmp_zoneless() is used.
