(http://svnweb.freebsd.org/socsvn?view=revision&revision=255272) * Remove xts_smallblock because it's not a part of the standard and crash dumps are larger than 16B. (http://svnweb.freebsd.org/socsvn?view=revision&revision=255276) * Import pefs' key derivation function. (http://svnweb.freebsd.org/socsvn?view=revision&revision=255309) Till the end of mid-term evaluation (this Friday) I plan to fix the encryption algorithm to encrypt 512B long chunks in 4096B long data units. Then we will have basically working crash dumps encryption which is ready to use with pefs.
