Dear Ryusuke: Thank you for the quick support. Nilfs2 is awesome.
It seems there is still overhead on the checkpoints. But if I set the protection period to 0, each time the cleanerd is invoked, it should clean all the obsolete data blocks. Is what I say right? Thanks again.

I don't think it's achieved just by setting protection period to zero, but it's possible by rewriting a few functions in cleanerd.c. Of course, it's not exactly the same because nilfs kernel codes still performs additional work needed to create checkpoints. But, does it have a point for you?
