From 2032a1914d72e4de89280e179c782566cafc163a Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 25 Jun 2009 07:27:25 -0400 Subject: [PATCH] mount.cifs: add support for sending IPv6 scope ID to kernel When getaddrinfo returns an IPv6 address with a non-zero scope_id, send that to the kernel appended to the address with a '%' delimiter. This allows people to mount servers via their link-local IPv6 addresses (given a kernel that understands this address format, of course).
