    As I understand it, that driver used to work right with SLAB, then
    oopsed with SLUB, and now works okay again with the page_mapping patch?

    I'm unclear how it comes about that you removed "all other such strange
    slab uses in other arches", yet missed this? That suggests there may
    be further unexpected uses.

    It worries me that any use which catches you by surprise has to be
    fixed up in the caller, rather than in slub itself: slab/slub is a
    service, not a master. But I'm rather repeating myself.
