    I was giving 2.6.0-test2 a spin, and run into a few issues with
    loopback crypto:

    First of all, in util-linux 2.12 the keybits option is gone, and the
    number of keybits is fixed to 256 (even though some algorithms in the
    kernel support more). Is this a temporary thing or a design decision?

    Moving to the slightly more ontopic stuff for lk@vger: Is access to
    the cryptoapi algorithms exposed to userspace yet? I wanted to have
    losetup/mount hash the passphrase before passing it to the kernel, and
    it seems silly to actually put a separate hashing algorithm in
    util-linux when they're there in the kernel anyway.

    Thirdly, has the encryption setup changed again since 2.4.x with hvr's
    testing cryptoapi stuff? I have a filesystem encrypted with 256 bits
    serpent, yet it won't decrypt using 2.6.0-test2 and util-linux 2.12.

    Lastly: Why the move from a /proc/crypto directory containing files
    for all the algorithms to one monolithic /proc/crypto file? Isn't the
    former a lot nicer from the userspace programmer's point of view?
