* It's a bit weird to associate a kthread with a css without being
  specific.  If what's needed is a generic association (this kthread
  is temporarily servicing this cgroup), it should be associated with
  the cgroup.  But, I think it'd be better to make it specific instead
  - ie. kthread_set_io_css().

kthread[_set]_blkcg_css() probably is a more consistent name.

Sorry, I meant kthread[_associate]_blkcg() so that it's consistent
with bio[_associate]_blkcg().

Thanks.
