77d2f7c247 staging: comedi: das800: 'dev->subdevices + 0' is already known 
There is no need to calculate the subdevice for the call to
das800_cancel. The variable 's' in this function is set to the
'dev->read_subdev' which is the same as 'dev->subdevices + 0'.

14c9fda5c4 staging: ramster: place ramster codebase on top of new zcache2 codebase 
[V2: rebased to apply to 20120905 staging-next, no other changes]

This slightly modified ramster codebase is now built entirely on zcache2
and all ramster-specific code is fully contained in a subdirectory.

Ramster extends zcache2 to allow pages compressed via zcache2 to be
"load-balanced" across machines in a cluster.  Control and data communication
is done via kernel sockets, and cluster configuration and management is
heavily leveraged from the ocfs2 cluster filesystem.

There are no new features since the codebase introduced into staging at 3.4.
Some cleanup was performed though:
 1) Interfaces directly with new zbud
 2) Debugfs now used instead of sysfs where possible.  Sysfs still
    used where necessary for userland cluster configuration.

Ramster is very much a work-in-progress but also does really work!

RAMSTER HIGH LEVEL OVERVIEW (from original V5 posting in Feb 2012)

RAMster implements peer-to-peer transcendent memory, allowing a "cluster" of
kernels to dynamically pool their RAM so that a RAM-hungry workload on one
machine can temporarily and transparently utilize RAM on another machine which
is presumably idle or running a non-RAM-hungry workload.  Other than the
already-merged cleancache patchset and frontswap patchset, no core kernel
changes are currently required.

(Note that, unlike previous public descriptions of RAMster, this implementation
does NOT require synchronous "gets" or core networking changes. As of V5,
it also co-exists with ocfs2.)

RAMster combines a clustering and messaging foundation based on the ocfs2
cluster layer with the in-kernel compression implementation of zcache2, and
adds code to glue them together.  When a page is "put" to RAMster, it is
compressed and stored locally.  Periodically, a thread will "remotify" these
pages by sending them via messages to a remote machine.  When the page is
later needed as indicated by a page fault, a "get" is issued.  If the data
is local, it is uncompressed and the fault is resolved.  If the data is
remote, a message is sent to fetch the data and the faulting thread sleeps;
when the data arrives, the thread awakens, the data is decompressed and
the fault is resolved.

As of V5, clusters up to eight nodes are supported; each node can remotify
pages to one specified node, so clusters can be configured as clients to
a "memory server".  Some simple policy is in place that will need to be
refined over time.  Larger clusters and fault-resistant protocols can also
be added over time.
