From ee86588960e259760236a537323d5c7d945e378c Mon Sep 17 00:00:00 2001 From: "Mike Rapoport (IBM)" Date: Wed, 1 Feb 2023 11:41:55 +0200 Subject: docs/mm: remove useless markup It is enough to use a file name to cross-reference another rst document. Jon says: The right things will happen in the HTML output, readers of the plain-text will know immediately where to go, and we don't have to add the label clutter. Drop reference markup and unnecessary labels and use plain file names.
