  • 28dbc4b6a   memcg: memory cgroup resource counters for hierarchy ... Browse Code »

    Add support for building hierarchies in resource counters. Cgroups allows
    us to build a deep hierarchy, but we currently don't link the resource
    counters belonging to the memory controller control groups, in the same
    fashion as the corresponding cgroup entries in the cgroup hierarchy. This
    patch provides the infrastructure for resource counters that have the same
    hiearchy as their cgroup counter parts.

    These set of patches are based on the resource counter hiearchy patches
    posted by Pavel Emelianov.

    NOTE: Building hiearchies is expensive, deeper hierarchies imply charging
    the all the way up to the root. It is known that hiearchies are
    expensive, so the user needs to be careful and aware of the trade-offs
    before creating very deep ones.

  • 856c13aa1   cgroup files: convert res_counter_write() to be a cgroups write_string() handler ... Browse Code »

    Currently res_counter_write() is a raw file handler even though it's
    ultimately taking a number, since in some cases it wants to
    pre-process the string when converting it to a number.

    This patch converts res_counter_write() from a raw file handler to a
    write_string() handler; this allows some of the boilerplate
    copying/locking/checking to be removed, and simplies the cleanup path,
    since these functions are now performed by the cgroups framework.

    This field is the maximal value of the usage one since the counter creation
    (or since the latest reset).

    To reset this to the usage value simply write anything to the appropriate
    cgroup file.

  • 0eea10301   Memory controller improve user interface ... Browse Code »

    Change the interface to use bytes instead of pages. Page sizes can vary
    across platforms and configurations. A new strategy routine has been added
    to the resource counters infrastructure to format the data as desired.

    Suggested by David Rientjes, Andrew Morton and Herbert Poetzl

    Tested on a UML setup with the config for memory control enabled.

    With fixes from David Rientjes

    Introduce generic structures and routines for resource accounting.

    Each resource accounting cgroup is supposed to aggregate it,
    cgroup_subsystem_state and its resource-specific members within.
