Subject: mm/damon: add default allow/reject behavior fields to struct damos
Date: Tue, 4 Mar 2025 13:19:10 -0800

Current default allow/reject behavior of filters handling stage has made
before introduction of the allow behavior.  For allow-filters usage, it is
confusing and inefficient.

It is more intuitive to decide the default filtering stage allow/reject
behavior as opposite to the last filter's behavior.  The decision should
be made separately for core and operations layers' filtering stages, since
last core layer-handled filter is not really a last filter if there are
operations layer handling filters.

Keeping separate decisions for the two categories can make the logic
simpler.  Add fields for storing the two decisions.
