[PATCH 0/5] wait_task_* cleanups V2

[Vitaly Mayatskikh <v.mayatskih@gmail.com>]

These patches eliminate duplicate code for filling rusage and siginfo
structures in wait_task_*() routines. The work is based on top of recent
Oleg's changes in do_wait().

I'm running kernel with these changes on my laptop for one day, nothing
exploded (yet).

More changes to come.

Vitaly Mayatskikh (5):
  Split wait_noreap_copyout()
  Use copy_wait_opts_to_user() in wait_task_stopped()
  Use copy_wait_opts_to_user() in do_wait()
  Use copy_wait_opts_to_user() in wait_task_zombie()
  Use copy_wait_opts_to_user() in wait_task_continued()
