[Devel] [PATCH v9 0/9] Request for inclusion: per-cgroup tcp memory pressure controls

[Glauber Costa]

Hi,

This series fixes all the few comments raised in the last round,
and seem to have acquired consensus from the memcg side.

Dave, do you think it is acceptable now from the networking PoV?
In case positive, would you prefer merging this trough your tree,
or acking this so a cgroup maintainer can do it?


Thanks

Glauber Costa (9):
  Basic kernel memory functionality for the Memory Controller
  foundations of per-cgroup memory pressure controlling.
  socket: initial cgroup code.
  tcp memory pressure controls
  per-netns ipv4 sysctl_tcp_mem
  tcp buffer limitation: per-cgroup limit
  Display current tcp memory allocation in kmem cgroup
  Display current tcp failcnt in kmem cgroup
  Display maximum tcp memory allocation in kmem cgroup
