Subject: Re: algorithm for half-md4 used in htree directories

Oh, and taking a quick look at your program, here's at least one of
the bugs:

static void calculate(char *name) {
                      ^^^^^^^^^^
...
    __ext4fs_dirhash(name, sizeof(name), &hinfo);
                           ^^^^^^^^^^^^

With apologies to the movie "The Princess Bride"[1]:

    You fell victim to one of the classic blunders!  The most famous
    is to never get involved in a land war in Asia, but only slightly
    less well-known is this: 'taking the size of a C pointer is
    generally not what you had wanted to do'!  :-)
