  • a52633d8e   mm, vmscan: move lru_lock to the node ... Browse Code »

    Node-based reclaim requires node-based LRUs and locking. This is a
    preparation patch that just moves the lru_lock to the node so later
    patches are easier to review. It is a mechanical change but note this
    patch makes contention worse because the LRU lock is hotter and direct
    reclaim and kswapd can contend on the same lock even when reclaiming
    from different zones.

  • 2bdbc5bc1   Documentation/memcg: update kmem limit doc as codes behavior ... Browse Code »

    The restriction of kmem setting is not there anymore because the
    accounting is enabled by default even in the cgroup v1 - see
    b313aeee2509 ("mm: memcontrol: enable kmem accounting for all
    cgroups in the legacy hierarchy").

    Update docs accordingly.

    Pull cgroup updates from Tejun Heo:
    "cgroup changes for v4.6-rc1. No userland visible behavior changes in
    this pull request. I'll send out a separate pull request for the
    addition of cgroup namespace support.

    - The biggest change is the revamping of cgroup core task migration
    and controller handling logic. There are quite a few places where
    controllers and tasks are manipulated. Previously, many of those
    places implemented custom operations for each specific use case
    assuming specific starting conditions. While this worked, it makes
    the code fragile and difficult to follow.

    The bulk of this pull request restructures these operations so that
    most related operations are performed through common helpers which
    implement recursive (subtrees are always processed consistently)
    and idempotent (they make cgroup hierarchy converge to the target
    state rather than performing operations assuming specific starting
    conditions). This makes the code a lot easier to understand,
    verify and extend.

    - Implicit controller support is added. This is primarily for using
    perf_event on the v2 hierarchy so that perf can match cgroup v2
    path without requiring the user to do anything special. The kernel
    portion of perf_event changes is acked but userland changes are
    still pending review.

    - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in
    certain environments.

    - There is a regression introduced during v4.4 devel cycle where
    attempts to migrate zombie tasks can mess up internal object
    management. This was fixed earlier this week and included in this
    pull request w/ stable cc'd.

    - Misc non-critical fixes and improvements"
