I dont see anything in there at first glance that would cause slub to
increase its percpu usage. This is straight upstream?
Try to just comment out the BUILD_BUG_ON. I had it misfire before and
fixed the formulae to no longer give false positives. Maybe that is
another case. Tejun wanted that but never was able to give me an exact
formular to check for.
At the Ottawa Linux Symposium right now so responses may be delayed.
