From e4cabca54911a6be6f2e80e48fa497c7e19019a5 Mon Sep 17 00:00:00 2001 From: Craig Gallek Date: Tue, 25 Oct 2016 18:08:49 -0400 Subject: [PATCH] inet: Fix missing return value in inet6_hash As part of a series to implement faster SO_REUSEPORT lookups, commit 086c653f5862 ("sock: struct proto hash function may error") added return values to protocol hash functions and commit 496611d7b5ea ("inet: create IPv6-equivalent inet_hash function") implemented a new hash function for IPv6. However, the latter does not respect the former's convention. This properly propagates the hash errors in the IPv6 case.
