current some cgroup struct are protected by RCU.
struct protected by RCU:
struct css_set, struct cgroup_subsys_state, struct cgroup
pointer protected by RCU:
struct task_struct.cgroups, struct css_set.subsys[*],
struct cgroup_subsys_state.cgroup
the last two pointers are readonly pointer!
these patches are fix these structs, and pointers. And a faker:
struct cgroup_subsys.root
Not cleanup all yet.
Thanx, Lai
