Subject: [merged mm-stable] documentation-zram-remove-sections-numbering.patch removed from -mm tree
Date: Thu, 06 Aug 2026 19:02:42 -0700 [thread overview]
Message-ID: <20260807020242.836DD1F00A3A@smtp.kernel.org> (raw)
The quilt patch titled
Subject: Documentation: zram: remove sections numbering
has been removed from the -mm tree. Its filename was
documentation-zram-remove-sections-numbering.patch
This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
------------------------------------------------------
From: Sergey Senozhatsky <senozhatsky@chromium.org>
Subject: Documentation: zram: remove sections numbering
Date: Tue, 28 Jul 2026 11:12:11 +0900
Those numbers are difficult to maintain and in fact
we can refer to sections by their names (in html).
