Memory controller: resource counters
...
With fixes from David Rientjes <rientjes@google.com >
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.

memcgroup: temporarily revert swapoff mod
...
This patch precisely reverts the "swapoff: scan ptes preemptibly" patch
just presented. It's a temporary measure to allow existing memory
controller patches to apply without rejects: in due course they should be
rendered down into one sensible patch, and this reversion disappear.

cgroups: move cgroups destroy() callbacks to cgroup_diput()
...
Move the calls to the cgroup subsystem destroy() methods from
cgroup_rmdir() to cgroup_diput(). This allows control file reads and
writes to access their subsystem state without having to be concerned with
locking against cgroup destruction - the control file dentry will keep the
cgroup and its subsystem state objects alive until the file is closed.
The documentation is updated to reflect the changed semantics of destroy();
additionally the locking comments for destroy() and some other methods were
clarified and decrustified.

Make kernel-doc warn when a function/struct/union/typedef does not contain
a properly formatted short description, such as:
* scsi_devinfo: set up the dynamic device list
or
* scsi_devinfo -
This warning is only generated when verbose (-v) mode is used.
Also explain the -v command line option in the -h output.
