From 3a69f1635769e976151625798cc6597301150296 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Sat, 12 Jul 2025 12:50:14 -0700 Subject: [PATCH] mm/damon/core: destroy targets when kdamond_fn() finish When kdamond_fn() completes, the targets are kept. Those are kept to let callers do additional cleanups if they need. There are no such additional cleanups though. DAMON sysfs interface deallocates those in before_terminate() callback, to reduce unnecessary memory usage, for [f]vaddr use case. Just destroy the targets for every case in the core layer. This saves more memory and simplifies the logic.
