Subject: Re: [PATCH v2 1/2] lib/htree: Add locking interface to new Hash Tree

Dear, Greg Kroah-Hartman
Thank you for your reply email.

My first email(PATCH v1) is at the below link:
https://mail.google.com/mail/u/0/?tab=rm&ogbl#label/htree/FMfcgzQVxtmfRqXCVrDZjsJBdddbPLCV
[PATCH v1 1/2] lib/htree: Implementation of new Hash Tree

I missed you in the first email above.
Since I've been working on something called a new Hash Table, it may
not be needed in the kernel right now.
Since it is not currently implemented in the kernel, I have been
thinking a lot about how to release it.
I sent it as a patch file, but since there was too much content,
So, I attached the github address and PDF separately.
I'm very sorry if this doesn't meet the current patch standards.
However, I would like you to check the contents of my first email and
reply to me regarding the technical details.
I want to prove that my Hash Tree is superior.
I know you're busy, but please review it again.
Thanks.
