Ah, thanks for letting me know.

One minor question regarding your patch though: it hasn't got a
destroy_work_on_stack(). Isn't one needed because of
  INIT_WORK_ONSTACK() -> __INIT_WORK() -> __init_work() ->
  debug_object_init_on_stack() ?
At least work_on_cpu() destroys its local work_struct that way...


Thanks,

Nicolai
