>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).
