the same kernel mappings).

This patch provides the RG core and numtasks controller as container
subsystems, intended as an example of how to implement a more complex
resource control system over generic process containers. The changes
to the core involve primarily removing the group management, task
membership and configfs s
This patch creates a generic process container system based on (and
parallel top) the cpusets code. At a coarse level it was created by
copying kernel/cpuset.c, doing s/cpuset/container/g, and stripping out any
code that was cpuset-specific rather than applicable to any process
container subsystem
This is intended as a simple illustration of how a virtual server
system could be integrated with generic containers, and hence take
advantage of other resource-control efforts. A real implementation
would probably allow parameters such as configuring what kinds of
namespace creations triggered new

This example demonstrates how to use the generic container subsystem

Now that relocation of the VDSO for COMPAT_VDSO users is done at

Move the page walker code to lib/
This lets it get shared outside of proc/ and linked in only when
needed.

Make /proc/pid/smaps optional under CONFIG_EMBEDDED
