Here's the quote (from the "diff -u" section [pg 12] of the December 2004 LJ:

"Cryptoloop is very likely to be dropped from 2.6 unless Andrew Morton
decides to wait to remove the code in 2.7; either way it seems clear
that cryptoloop is on the way out. The feature, intended to allow the
user to mount encrypted filesystems over loopback, is apparently buggy
and unmaintained, as well as having significant security problems. And
as far as Andrew is concerned, it is this security question that dooms
cryptoloop. Better to have no feature, he says, than a feature that
falsely claims to provide real security. The argument, put forward by
a number of developers, that such major changes as removing a feature
should never occur in a stable series, is being heard, but it seems
that this may only delay the inevitable. Unless someone steps up to
maintain it and fix the security holes, cryptoloop probably will not
last much longer"
