    Seeing as I didn't notice this patchest changed XFS (where's the cc?)
    until I saw hch's question I'd appreciate a pointer to that discussion
    as it's long been deleted from my mailbox.

    FWIW, I happen to agree with Christoph (hch) that the shouting
    macros are an ugly step backwards, esp. given that is replacing:

    #define per_cpu_ptr(ptr, cpu) percpu_ptr((ptr), (cpu))

    a set of lowercase macros....
