The following series implements support for named cgroup hierarchies,
and for cgroup hierarchies that have no bound subsystems.
This is a subset of the patch series that I sent out as an RFC earlier
in the month; I'm not pushing the additional support for
multiply-bound hierarchies at this point.
Support named cgroups hierarchies
To simplify referring to cgroup hierarchies in mount statements, and
to allow disambiguation in the presence of empty hierarchies and
multiply-bindable subsystems this patch adds support for naming a new
cgroup hierarchy via the name= mount option
A pre-existing
Move the cgroup debug subsys into cgroup.c to access internal state
While it's architecturally clean to have the cgroup debug subsystem be
completely independent of the cgroups framework, it limits its
usefulness for debugging the contents of internal data structures.
Move the debug subsystem
Add a back-pointer from struct cg_cgroup_link to struct cgroup
Currently the cgroups code makes the assumption that the subsystem
pointers in a struct css_set uniquely identify the hierarchy-cgroup
mappings associated with the css_set; and there's no way to directly
identify the associated set of
Allow cgroup hierarchies to be created with no bound subsystems
This patch removes the restriction that a cgroup hierarchy must have
at least one bound subsystem. The mount option none is treated as
an explicit request for no bound subsystems.

This is the latest version of my patch set enabling c/r for sockets. I
chose to send only the UNIX patch and supporting changes to concentrate
on that as the INET patch will need more work.
This set introduces three c/r-specific helper routines (patches 1-3), a
more general sock_bind() helper to
This moves the meat out of the bind() syscall into a helper function that
performs security_socket_bind() and then sock-ops-bind(). This allows a
unification of this behavior between the syscall and the pending socket
restart logic.

This patch adds basic checkpoint/restart support for AF_UNIX sockets. It
has been tested with a single and multiple processes, and with data inflight
at the time of checkpoint. It supports socketpair()s, path-based, and
abstract sockets.
