Subject: [PATCH AUTOSEL 5.13 14/14] cryptoloop: add a deprecation warning
Date: Mon, 30 Aug 2021 07:59:42 -0400 [thread overview]
Message-ID: <20210830115942.1017300-14-sashal@kernel.org> (raw)
In-Reply-To: <20210830115942.1017300-1-sashal@kernel.org>
From: Christoph Hellwig <hch@lst.de>
[ Upstream commit 222013f9ac30b9cec44301daa8dbd0aae38abffb ]
Support for cryptoloop has been officially marked broken and deprecated
in favor of dm-crypt (which supports the same broken algorithms if
needed) in Linux 2.6.4 (released in March 2004), and support for it has
been entirely removed from losetup in util-linux 2.23 (released in April
2013). Add a warning and a deprecation schedule.
