Oops,  I am sorry, my bad. I copied the clause literally in my printf
and ended up printing
!get_array_length(....). With that corrected, it is "0" at both places.

Yes,  the PIDTYPE_MAX enum is equal  to 4.  Setting 'plen' to 4 seems to work.
So, it seems like a problem with get_array_length.

I will get you the dump/vmlinux files as soon as I can upload it
someplace (yousendit is acting up).
