------------------------------------------------------ From: Enze Li lienze@kylinos.cn Subject: mm/damon/core: fix potential memory leak by cleaning ops_filter in damon_destroy_scheme Date: Tue, 14 Oct 2025 16:42:25 +0800

Currently, damon_destroy_scheme() only cleans up the filter list but leaves ops_filter untouched, which could lead to memory leaks when a scheme is destroyed.

This patch ensures both filter and ops_filter are properly freed in damon_destroy_scheme(), preventing potential memory leaks.
