Something is telling me finding a 64 core system with a suitable
workload to try this could be a good thing. Wish I had one at my
disposal.
Maybe on big NUMA machines, we might prefer to spread the rwlock array on
multiple nodes (ie using vmalloc() instead of kmalloc())
After my patch, it is true all rwlocks are on one memory node. Not exactly
optimal :(
But if it was an issue, the spinlock array used in IP route cache would have
the same problem and *someone* should already have complained...
