If I didn't worry about wiping out a filesystem, then using cryptoloop would be easier than to interface cryptoapi inside the swap methods to leave the header in cleartext, so that it can be still checked for a magic number before starting writing into it. (plus interfacing swap with cryptoapi makes suspend/resume life easier too) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
