[Devel] [PATCH v7 0/8] Request for inclusion: tcp memory buffers

[Glauber Costa]

Hi Andrew,

This series was extensively reviewed over the past month, and after
all major comments were merged, I feel it is ready for inclusion when
the next merge window opens. Minor fixes will be provided if they
prove to be necessary.

You can see the most recent past discussions at:

It basically lays the foundation for kernel memory limitation as a
general framework, and uses it to control the existent tcp memory pressure
thresholds in a per-cgroup way.

Follow up patches are expected for soft limits, which are not handled.

Please consider this for inclusion in your tree

Thanks,

  Basic kernel memory functionality for the Memory Controller
  socket: initial cgroup code.
  foundations of per-cgroup memory pressure controlling.
  per-cgroup tcp buffers control
