Is it possible to separate these two features into two different patch
sets. I would like to apply the softirq changes first, and then apply
the slub changes.

Although it looks as though the first half is softirq only 1-8, and the
second half is slub related 9-16. If that's the case, I'll just pull in
1-8 first, play with them, and then do 9-16.

Thanks,
