Subject: mm/damon/core: pass per-region filter-passed bytes to damos_walk_control->walk_fn()
Date: Mon, 6 Jan 2025 11:33:57 -0800

Total size of memory that passed DAMON operations set layer-handled DAMOS
filters per scheme is provided to DAMON core API and ABI (sysfs interface)
users.  Having it per-region in non-accumulated way can provide it in
finer granularity.  Provide it to damos_walk() core API users, by passing
the data to damos_walk_control->walk_fn().
