[ Upstream commit83ed7d1fe2] My randconfig builds came across an old missing dependency for ILA: ERROR: "dst_cache_set_ip6" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_get" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_init" [net/ipv6/ila/ila.ko] undefined! ERROR: "dst_cache_destroy" [net/ipv6/ila/ila.ko] undefined! We almost never run into this by accident because randconfig builds end up selecting DST_CACHE from some other tunnel protocol, and this one appears to be the only one missing the explicit 'select'. >From all I can tell, this problem first appeared in linux-4.9 when dst_cache support got added to ILA.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
