[PATCH v3 3/3] docs/admin-guide/mm: remove useless markup
From: Mike Rapoport
Date: Wed Feb 01 2023 - 04:42:39 EST
From: "Mike Rapoport (IBM)" <rppt@xxxxxxxxxx>
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.
