Subject: mm/damon: update outdated comment about DAMOS filter handling
Date: Tue, 21 Jul 2026 07:00:08 -0700

The kernel-doc comment above enum damos_filter_type states that only the
anon and memcg type filters are handled by damon_operations (and therefore
accounted as 'tried'), and that DAMON_OPS_VADDR and DAMON_OPS_FVADDR do
not support those two filter types.

Neither is accurate anymore.  damos_filter_for_ops() routes every filter
type except ADDR and TARGET to the operations layer, and the VADDR and
FVADDR operations (the latter being a copy of the former) handle all of
those types through damos_folio_filter_match() / damos_va_filter_out(). 
Update the comment to match the code.
