objpool, a scalable and lockless ring-array based object pool, was
introduced to replace the original freelist (a LIFO queue based on
singly linked list) to improve kretprobe scalability.

kretprobe is using freelist to manage return-instances, but freelist,
as LIFO queue based on singly linked list, scales badly and reduces
the overall throughput of kretprobed routines, especially for high
contention scenarios.
