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

These patches aren't sequence numbered. In what order should they be
applied?

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
