Hi, This patchset implements per-cgroup tcp memory pressure controls. It did not change significantly since last submission: rather, it just merges the comments Kame had. Most of them are style-related and/or Documentation, but there are two real bugs he managed to spot (thanks) Please let me know if there is anything else I should address.
