This patch set implements secure delete for ext4. New flags have been added to ext4_free_blocks and ext4_delete_entry that cause the data blocks and directory entries to be zeroed before they are released. Files that have the secure remove attribute flag on will have their data and directory entries zeroed when they are deleted.
