From 0bfd4586855cf6919d025b5914be212fd4cd27b5 Mon Sep 17 00:00:00 2001 From: Nico Pache Date: Mon, 17 Mar 2025 17:04:03 -0600 Subject: [PATCH] MM documentation: add "Unaccepted" meminfo entry 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.
