I guess these two patches work.  But it sure looks like the long way around
as a way of changing the argument to attach_pid.

As incremental step couldn't we just have changed the callers to:
attach_pid(task, type, find_pid(nr)).

Not that I think changing all of the callers to actually pass in the correct
struct pid is going to be much of a problem.

It just seems like a whole lot of unnecessary thrash to change them
all to find_attach_pid and then back to attach_pid.
