Call synchronize_sched() when kernfs_node is updated since tracepoints are protected by rcu_read_lock_sched.
Adding synchronize_sched() to operations which can be triggered from userland usually turns out to be problematic. If this can't be solved any other way, I think the right thing to do is replacing the path with cgroup id as Christoph suggested.
Agreed. The path is not that important, right?
