Currently the virCgroupPtr struct contains 3 pieces of information - path - path of the cgroup, relative to current process' cgroup placement - placement - current process' placement in each controller - mounts - mount point of each controller When reading/writing cgroup settings, the path & placement strings are combined to form the file path. This approach only works if we assume all cgroups will be relative to the current process' cgroup placement. To allow support for managing cgroups at any place in the heirarchy a change is needed. The 'placement' data should reflect the absolute path to the cgroup, and the 'path' value should no longer be used to form the paths to the cgroup attribute files. Signed-off-by: NDaniel P.
