[PATCH 0/6] ipv4: tcp_memcontrol and userns sysctls

[ebiederm-aS9lmoZGLiVWk0Htik3J/w@public.gmane.org (Eric W. Biederman)]

While looking into allowing the ipv4 sysctls to be used in a network
namespace I stumbled upon the mess that is tcp_memcontrol.

I remove the dead code, broken code, and excessive abstraction in the
tcp_memcontrols then I clean up up and allow in the user namespace the
per net ipv4 sysctls.

Eric W. Biederman (6):
      tcp_memcontrol: Remove tcp_max_memory
      tcp_memcontrol: Remove setting cgroup settings via sysctl
      tcp_memcontrol: Remove the per netns control.
      tcp_memcontrol: Kill struct tcp_memcontrol
      ipv4: Use math to point per net sysctls into the appropriate struct net.
      ipv4: Allow unprivileged users to use per net sysctls
