Subject: Query on skip_onerr field in struct cpuhp_step

Hi All,

This is about one of field in struct cpuhp_step

* @skip_onerr: Do not invoke the functions on error rollback
  *              Will go away once the notifiers are gone
         bool                    skip_onerr;

Why this field was introduced, can anyone explain the history behind ? 
As i don't see it being set from anywhere

If it is specifically was dependent on notifiers, did we missed to 
remove it as the notifiers are gone or the usecase still there?
And If it is still valid, in what scenario i would not want my callback 
to be called in rollback path?
