Are there any filesystems that have secure deletion as a feature?



There's many 3rd party tools people have designed to perform secure deletion, but I don't know of any filesystems where secure deletion is built in. In fact, secure deletion has to work around features of filesystems like journaling that (inadvertently) make secure deletion more difficult. Are there any filesystems that allow secure deletion as a feature?


My own research revealed a set of patches to ext4 by an Allison Henderson, but the last references I can find for this are from 2011. They appear to be not perfect, but far better than the complete non-wipe that happens in most, if not all modern filesystems.
