This patch series introduces a scalable and lockless ring-array based
object pool to improve scalability of kretprobed routines.

v11:
  *) patchset rebased to branch probes/core of linux-trace.git
  *) objpool: objpool_fini optimized for better code readability
  *) test_objpool: asynchronous releasing of objpool now covered

wuqiang.matt (5):
  lib: objpool added: ring-array based lockless MPMC
  lib: objpool test module added
  kprobes: kretprobe scalability improvement with objpool
  kprobes: freelist.h removed
  MAINTAINERS: objpool added
