We must decouple stackdepot from page_owner as much as possible, not add extra dependencies by sharing variables between the two. What you need here is a pair of xxx_iter_start()/xxx_iter_next() functions in stackdepot.c that will hold the iteration state in a struct and return the next stack trace. The threshold value can also be part of that struct.
