Thank you for your reply. The title of this patch is indeed not good. We are planning to rename it as "mm: page_alloc: fix missed updates of lowmem_reserve in adjust_managed_page_count". Is it OK? < The subject of this patch is really poor. "some memory information"? < < considering the text below is so much more descriptive, could we have a < meaningful subject? You will not get the proper people looking at this < without a decent subject. At least make it "mm/page_alloc" ? Regarding Signed-off-by, we are sorry that we do not have a particular good way. When we are on the intranet, we use jd.com email. However, this email cannot send emails externally, so we used our own Gmail as the sending email. My name is Zihan Zhou, and zhouzihan30 is my internal ERP. I also rely on this account to submit information on the intranet. Do we have to prepare a new account for kernel submission? < Who are these people, really? < < https://www.kernel.org/doc/html/v6.12/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin < < Also, the Signed-off-by doesn't match the sending email (gmail vs < jd.com)?
