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.
