The problem here is that dump_in_progress is set by the dump
execution code which is invoked a little after this, and only
stays enabled as long as that function executes. Maybe what
you meant here is not dump_in_progress but something more like
dump_okay (which is currently a static in dump drivers code),
or a check if the dump function is set, indicating that
things are setup so that a dump would be taken ?
