Without this metadata, I got (while running 2.6.36)
# modprobe ni_pcimio
FATAL: Error inserting ni_pcimio (/.../ni_pcimio.ko):
Unknown symbol in module, or unknown parameter (see dmesg)
# dmesg | tail -n30
...
[ 2970.180691] ni_pcimio: Unknown symbol ni_tio_handle_interrupt (err 0)
[ 2970.181170] ni_pcimio: Unknown symbol ni_tio_set_mite_channel (err 0)
[ 2970.183127] ni_pcimio: Unknown symbol ni_tio_init_counter (err 0)
[ 2970.183562] ni_pcimio: Unknown symbol ni_tio_winsn (err 0)
(similar missing symbols)
...
Even though other Comedi modules were providing the symbols:
# grep ni_tio_handle_interrupt /proc/kallsyms
d82a45b1 t ni_tio_handle_interrupt [ni_tiocmd]
With the metadata macros, ni_pcimio loads successfully.
