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
