Linux 4.2 compat: follow_link() / put_link()
As of Linux 4.2 the kernel has completely retired the nameidata
structure. One of the few remaining consumers of this interface
were the follow_link() and put_link() callbacks.
This patch adds the required checks to configure to detect the
interface change and updates the functions accordingly. Migrating
to the simple_follow_link() interface was considered but was decided
against ironically due to the increased complexity.
It also should be noted that the kernel follow_link() and put_link()
interfaces changes several times after 4.1 and but before 4.2. This
means there is a narrow range of kernel commits which never appear
in an official tag of the Linux kernel which ZoL will not build.
