From f7f0d88b7d6da29d2b073740aa130685f0e18609 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Wed, 5 Mar 2025 14:27:29 -0800 Subject: [PATCH] mm/damon/core: expose damos_filter_for_ops() to DAMON kernel API callers damos_filter_for_ops() can be useful to avoid putting wrong type of filters in wrong place. Make it be exposed to DAMON kernel API callers.
