How do I allocate a port from within a kernel server? The documention
for hmap lists the following:

/* Create the port. */
r = port_allocate((task_t)task_self(), &port_name);

which can't possibly work, since task_self is not defined in the kernel.

I tried various combinations of current_task() and convert_task_to_port(),
none of which worked.

Could someone who has done this tell me how?
