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?
It can be, but we can print out the ino and userland can match that up with path if necessary.
Wouldn't be cgroup id the better choice?
