From b58f0e8f38c0a44afa59601a115bd231f23471e1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 28 May 2020 07:12:09 +0200 Subject: net: add sock_set_reuseaddr Add a helper to directly set the SO_REUSEADDR sockopt from kernel space without going through a fake uaccess. For this the iscsi target now has to formally depend on inet to avoid a mostly theoretical compile failure. For actual operation it already did depend on having ipv4 or ipv6 support.
