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.
