cryptoloop: add a deprecation warning
[ 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.
