From a8c2275493b866961f4429a741251c630c4fc6d7 Mon Sep 17 00:00:00 2001 From: Alexander Aring <alex.aring@gmail.com> Date: Sat, 21 Dec 2013 05:39:04 +0100 Subject: [PATCH] nfs: fix dead code of ipv6_addr_scope The correct way to check on IPV6_ADDR_SCOPE_LINKLOCAL is to check with the ipv6_addr_src_scope function. Currently this can't be work, because ipv6_addr_scope returns a int with a mask of IPV6_ADDR_SCOPE_MASK (0x00f0U) and IPV6_ADDR_SCOPE_LINKLOCAL is 0x02. So the condition is always false.
