update/bdflush whatever it is called should call
sys_bdflush(func = 1)
Which eventually calls sync_old_buffers.
Which could use a little bit of work to be jiffie wrap safe, and
int/long consistent, but is otherwise fine.
The process on my machine that does this is update and it is an old
trusted a.out process..
Why do you need to rewrite it?
