Subject: [RFC 0/5] Memory controller soft limit introduction (v3)

This patchset implements the basic changes required to implement soft limits
in the memory controller. A soft limit is a variation of the currently
supported hard limit feature. A memory cgroup can exceed it's soft limit
provided there is no contention for memory.

These patches were tested on a x86_64 box, by running a programs in parallel,
and checking their behaviour for various soft limit values.

These patches were developed on top of 2.6.26-rc5-mm3. Comments, suggestions,
criticism are all welcome!

A previous version of the patch can be found at

http://kerneltrap.org/mailarchive/linux-kernel/2008/2/19/904114

TODOs:

1. Distribute the excessive (non-contended) resources between groups
   in the ratio of their soft limits
2. Merge with KAMEZAWA's and YAMAMOTO's water mark and background reclaim
   patches in the long-term
