    Hello!

    > Comments welcome.

    I do not know what forced you to use BKL.

    But I daresay this is deadlock:

    + lock_kernel();
    + error = f_setown(filp, current->pid);
    + unlock_kernel();
    if (error) {
    write_unlock(&dn_lock);
    return error;

    Use of BKL when another spin lock is grabbed... It will deadlock
    each time when some dcahe op is made under BKL.
