[PATCH] docs: vm/page_owner: Use literal blocks for param description

[Akira Yokosawa]

Subject: [PATCH] docs: vm/page_owner: Use literal blocks for param description

Sphinx generates hard-to-read lists of parameters at the bottom
of the page.  Fix them by putting literal-block markers of "::"
in front of them.

Hello Andrew,

This is the first time I send a patch in your way.
So I'm not sure this works as I intend.
If anything goes wrong, please let me know.

This issue is in discussion in a linux-doc thread triggered by
a post from Haowen Bai [1]. (Warning: The thread looks confused
due to Haowen's unnecessary uses of In-Reply-To: headers.)
Jon suggested the route via your tree, but he keeps posting
to linux-doc.

Haowen's patch uses tables to improve the look of param lists.
I suggested him using literal blocks instead, but I failed to
hear any response. So I'm sending my version of the fix in your
way.

I believe this fix is worth for 5.18-rcX.

Side note 1: I see another patch queued for -next around here, which
has broken indents by white spaces.  You might want to fix or drop it.

Side note 2: page_owner.rst is not covered in MAINTAINERS.
You might want to add an entry, maybe, under "PAGE TABLE CHECK".

Again, if there is anything I can do better, please let me know.

Best,

        Akira
