  • The temp[1-*]_type attribute reports the temperature sensor type. Sensor type 1
    is described as "PII/Celeron Diode", which is quite restrictive; other CPUs
    may also have an embedded temperature sensor diode with similar characteristics.
    Change description to "CPU embedded diode" to be more generic.

  • Kmemleak patches

    Main features:
    - Handle percpu memory allocations (only scanning them, not actually
    reporting).
    - Memory hotplug support.

    Usability improvements:
    - Show the origin of early allocations.
    - Report previously found leaks even if kmemleak has been disabled by
    some error.

  • Andrew explains:

    - various misc stuff

    - Most of the rest of MM: memcg, threaded hugepages, others.

    - cpumask

    - kexec

    - kdump

    - some direct-io performance tweaking

    - radix-tree optimisations

    - new selftests code

    A note on this: often people will develop a new userspace-visible
    feature and will develop userspace code to exercise/test that
    feature. Then they merge the patch and the selftest code dies.
    Sometimes we paste it into the changelog. Sometimes the code gets
    thrown into Documentation/(!).

    This saddens me. So this patch creates a bare-bones framework which
    will henceforth allow me to ask people to include their test apps in
    the kernel tree so we can keep them alive. Then when people enhance
    or fix the feature, I can ask them to update the test app too.

    The infrastruture is terribly trivial at present - let's see how it
    evolves.

    - checkpoint/restart feature work.

    A note on this: this is a project by various mad Russians to perform
    c/r mainly from userspace, with various oddball helper code added
    into the kernel where the need is demonstrated.

    So rather than some large central lump of code, what we have is
    little bits and pieces popping up in various places which either
    expose something new or which permit something which is normally
    kernel-private to be modified.

    The overall project is an ongoing thing. I've judged that the size
    and scope of the thing means that we're more likely to be successful
    with it if we integrate the support into mainline piecemeal rather
    than allowing it all to develop out-of-tree.

    However I'm less confident than the developers that it will all
    eventually work! So what I'm asking them to do is to wrap each piece
    of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all
    eventually comes to tears and the project as a whole fails, it should
    be a simple matter to go through and delete all trace of it.

    This lot pretty much wraps up the -rc1 merge for me.

  • The mm->start_code/end_code, mm->start_data/end_data, mm->start_brk are
    involved into calculation of program text/data segment sizes (which might
    be seen in /proc//statm) and into brk() call final address.

    For restore we need to know all these values. While
    mm->start_code/end_code already present in /proc/$pid/stat, the rest
    members are not, so this patch brings them in.

    The restore procedure of these members is addressed in another patch using
    prctl().

  • The sysctl works on the current task's pid namespace, getting and setting
    its last_pid field.

    Writing is allowed for CAP_SYS_ADMIN-capable tasks thus making it possible
    to create a task with desired pid value. This ability is required badly
    for the checkpoint/restore in userspace.

    This approach suits all the parties for now.

  • The two memcg stats pgpgin/pgpgout have different meaning than the ones
    in vmstat, which indicates that we picked a bad naming for them.

    It might be late to change the stat name, but better documentation is
    always helpful.

  • Recent tools do not want to use /proc to retrieve module information. A few
    values are currently missing from sysfs to replace the information available
    in /proc/modules.

    This adds /sys/module/*/{coresize,initsize,taint} attributes.

    TAINT_PROPRIETARY_MODULE (P) and TAINT_OOT_MODULE (O) flags are both always
    shown now, and do no longer exclude each other, also in /proc/modules.

    Replace the open-coded sysfs attribute initializers with the __ATTR() macro.

    Add the new attributes to Documentation/ABI.

  • Enable/disable use of the dentry dir 'complete' flag via a mount option.
    This lets the admin control whether ceph uses the dcache to satisfy
    negative lookups or readdir when it has the entire directory contents in
    its cache.

    This is purely a performance optimization; correctness is guaranteed
    whether it is enabled or not.
