From: Zi Yan <ziy@nvidia.com>
Subject: fscrypt: stop setting PG_private on bounce page
Date: Sun, 13 Sep 2026 22:24:02 -0400

The pointer to a plain text folio is stored in bound_page->private and
cannot be NULL until the bounce_page is freed, making PG_private
redundant.

It prepares for a future commit that remove PG_private.

No functional change intended.
