Hello Masami,
I've udpated the objpool patch and did some function testings for X64 and
ARM64. Later I'll do the performance testings and more regressions.
Here are the changelogs:
1) new struct objpool_node added to represent the real percpu ring arrary
and struct objpool_slot now represents

Hello Masami,
Just got time for the new patch and got that ages[] was removed. ages[] is
introduced the way like 2-phase commit to keep consitency and must be kept.
Thinking of the following 2 cases that two cpu nodes are operating the same
objpool_slot simultaneously:
Case 1:
