  • a77aea920   cgroup: remove the ns_cgroup ... Browse Code »

    The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and
    leads to some problems:

    * cgroup creation is out-of-control
    * cgroup name can conflict when pids are looping
    * it is not possible to have a single process handling a lot of
    namespaces without falling in a exponential creation time
    * we may want to create a namespace without creating a cgroup

    The ns_cgroup was replaced by a compatibility flag 'clone_children',
    where a newly created cgroup will copy the parent cgroup values.
    The userspace has to manually create a cgroup and add a task to
    the 'tasks' file.

    This patch removes the ns_cgroup as suggested in the following thread:

    https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html

    The 'cgroup_clone' function is removed because it is no longer used.

    This is a userspace-visible change. Commit 45531757b45c ("cgroup: notify
    ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a
    printk warning users that the feature is planned for removal. Since that
    time we have heard from XXX users who were affected by this.

  • c650da23d   PM: Remove CONFIG_PM_VERBOSE ... Browse Code »

    Now that we have CONFIG_DYNAMIC_DEBUG there is no need for yet
    another flag causing dev_dbg() and pr_debug() statements in the
    core PM code to produce output. Moreover, CONFIG_PM_VERBOSE
    causes so much output to be generated that it's not really useful
    and almost no one sets it.
