Ok, I should have read all my emails before responding to the previous 
one.

But my response ends up being the same: I think your patch is fine, and I 
think you should drop the conditional flag. I don't think anybody _ever_ 
wants to run the same work entry on multiple CPU's at once. Anybody who 
wants parallelism needs to use multiple work entries _anyway_ (since the 
accidental parallelism you *can* get with a single one is really very 
accidental indeed).

Of course, it should be tested in -next for a while regardless. And talk 
to the networkng people, who are the main user of workqueues.
