| Subject: MM documentation: add "Unaccepted" meminfo entry |
| Date: Mon, 17 Mar 2025 17:04:03 -0600 |
| |
| Commit dcdfdd40fa82 ("mm: Add support for unaccepted memory") added a |
| entry to meminfo but did not document it in the proc.rst file. |
| |
| This counter tracks the amount of "Unaccepted" guest memory for some |
| Virtual Machine platforms, such as Intel TDX or AMD SEV-SNP. |
| |
| Add the missing entry in the documentation. |
