[PATCH v2 6/9] docs: cgroup-v1: use bullet lists for list of stat file tables

From: Bagas Sanjaya
Date: Thu Jan 05 2023 - 08:18:19 EST


The stat file section contains three tables, where the leading texts for
them are subsection heading. Organize them in the bullet list, while
demoting headings into normal text.

- event happens each time a page is unaccounted from the cgroup.
-swap # of bytes of swap usage
