I stumbled across this in fs/kernfs/dir.c:39.

        /* Reserve hash numbers 0, 1 and INT_MAX for magic directory entries */
        if (hash < 1)
                hash += 2;
        if (hash >= INT_MAX)
                hash = INT_MAX - 1;

Shouldn't that be (hash < 2), or is 1 not reserved?

Thanks,
Richard
