Mitsumasa-san, since you have the test rig ready, could you try the attached patch please? It scans the buffer cache several times, writing out all the dirty buffers for segment A first, then fsyncs it, then all dirty buffers for segment B, and so on. The patch is ugly, but if it proves to be helpful, we can spend the time to clean it up.
Thank you! It is interesting code, I test it.
By the way, my campany's colleague helps us to testing. If you have other idea, please send me patch or methods.
