    Subject[PATCH v8 0/9] per-cgroup tcp memory pressure controls
    Date
    Hi,

    This is my new attempt to fix all the concerns that were raised during
    the last iteration.

    I should highlight:
    1) proc information is kept intact. (although I kept the wrapper functions)
    it will be submitted as a follow up patch so it can get the attention it
    deserves
    2) sockets now hold a reference to memcg. sockets can be alive even after the
    task is gone, so we don't bother with between cgroups movements.
    To be able to release resources more easily in this cenario, the parent
    pointer in struct cg_proto was replaced by a memcg object. We then iterate
    through its pointer (which is cleaner anyway)

    The rest should be mostly the same except for small fixes and style changes.

    Glauber Costa (9):
    Basic kernel memory functionality for the Memory Controller
    foundations of per-cgroup memory pressure controlling.
    socket: initial cgroup code.

    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
