Subject: mm/damon/paddr: support only damos->ops_filters
Date: Tue, 4 Mar 2025 13:19:09 -0800
DAMON physical address space operation set implementation (paddr) started
handling both damos->filters and damos->ops_filters to avoid breakage
during the change for the ->ops_filters setup. Now the change is done, so
paddr's support of ->filters is only a waste that can safely be dropped.
Remove it.
