Hi, all.
Thank you for your comment.

As you say, I think the last patch was rather confusing. For this reason, I simply reconsidered it.
The attached patch just outputs a log like your advice on acquiring Huge Page.
It is possible to limit the log output trigger only when huge_pages=try, but is it better not to always output it?
Regards,
