  • 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.

  • 6a108a14f   kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT ... Browse Code »

    The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
    is used to configure any non-standard kernel with a much larger scope than
    only small devices.

    This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
    references to the option throughout the kernel. A new CONFIG_EMBEDDED
    option is added that automatically selects CONFIG_EXPERT when enabled and
    can be used in the future to isolate options that should only be
    considered for embedded systems (RISC architectures, SLOB, etc).

    Calling the option "EXPERT" more accurately represents its intention: only
    expert users who understand the impact of the configuration changes they
    are making should enable it.

  • 6acc7d485   MIPS: Fix and enhance built-in kernel command line ... Browse Code »

    Currently, MIPS kernels silently overwrite kernel command-line parameters
    hardcoded in CONFIG_CMDLINE by the ones received from firmware. Therefore,
    using firmware remains the only reliable method to transfer the
    command-line parameters, which is not always desirable or convenient, and
    the CONFIG_CMDLINE option is thereby effectively rendered useless.

    This patch fixes the problem described above and introduces a more flexible
    scheme of handling the kernel command line, in a manner identical to what is
    currently used for x86. The default behavior, i.e. when CONFIG_CMDLINE_BOOL
    is not defined, retains the existing semantics, and firmware command-line
    arguments override the hardcoded ones.

    [Ralf: I fixed up all the defconfig files so the stay unaffected by this
    change.]

  • f7ade3c16   MIPS: Get rid of CONFIG_CPU_HAS_LLSC ... Browse Code »

    CONFIG_CPU_HAS_LLSC duplicated the function of cpu_has_llsc for no good
    reason and and the results if the one was enabled and the other disabled
    was very unobvious. Remove it now that there are no more remaining users.
