Hello Jinpu,

Interesting. However, I see that wrote the following: "Firstly this wrong sequence raises two kernel warnings: 1st. WARNING at lib/percpu-recount.c:309 percpu_ref_kill_and_confirm called more than once 2nd. WARNING at lib/percpu-refcount.c:331". I haven't seen any of these kernel warnings ...

Thanks,

Bart.
