I can easily imagine an implementation of "replace_oom_score_adj"
which does not return the old value: so no, that name does not imply
that it will be returning the old value.  But since it does return
something, it's quite reasonable that what it returns is the old
value.

Whereas "test_set_oom_score_adj" tends to imply that it will set the
oom_score_adj only if it's currently zero.
