The percpu structure contains a spinlock and may be remotely accessed? You are aware that other percpu variables that share the same cacheline will be negatively impacted by accesses from other processors? The role of percpu areas are to have memory areas where the code can expect that cachelines are exclusively there for that processor. How frequent are the remote accesses? If this is rare then ok.
