In theory the sorting should be performed by the underlying disk scheduler, however, in practice the dm-crypt is such a device-mapper target that provides transparent encryption of block devices using the new Linux 2.6 cryptoapi. The user can basically specify one of the symmetric ciphers, a key (of any allowed size), an iv generation mode and then the user can create a new block device in /dev. Writes to this device will be encrypted and The Linux Device Manager's dm-crypt allows for transparent disk encryption and does so quite well, but until now hasn't properly supported zoned block devices. Thankfully from Western Digital is now support that was queued on Monday for dm-crypt zoned block device support. This code is now within the Linux Device Mapper Git branch of material
