  1. config-linux: mark memory.kernel[TCP] as NOT RECOMMENDED

    Per-cgroup kernel memory accounting (and explicit limiting) is
    problematic in the Linux kernel for too many reasons to quote here.
    Besides, cgroup v2 does not even have a kernel memory limit knob,
    and the one in cgroup v1 is made obsoleted in kernel v5.4 [1].
    
    Mark memory.kernel and memory.kernelTCP as NOT RECOMMENDED, in additon
    to OPTIONAL. This is a way to say "we do not anyone (runtimes or users)
    to set those limits, unless they have good understanding and strong
    reasons to do so".
