[$] Three sessions on memory control groups

Memory control groups allow the system administrator to impose memory-uselimits on the members of control groups. In many ways, these limits behavelike the overall limit on available memory, but there are also somedifferences. The behavior of the memory controller also changed with theadvent of the version-2 control-group API, creating problems for at leastone significant user. Three sessions held in the memory-management track ofthe Linux Storage, Filesystem, and Memory-Management Summit explored someof these problems.
