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....
