kiobuf questions

[BenHanokh Gabriel <gabriel@SANgate.com>]

hi

i'm trying to understand the role of the kiobuf struct in the io
subsystem.

there are 2 fields i failed to see any reference to :
end_io  and
wait_queue 

now, the documentation says that this is a completion callback , but i
never saw anyone using it.

the same goes for the wait_queue, i didn't see any code utilizing it(
except for the kiobuf_wait_for_io() which noone uses )
