From 69bbaa0fdddc01233c488d73a041a1e122655738 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Sun, 22 Dec 2024 15:12:22 -0800 Subject: [PATCH] mm/damon/core: fix ignored quota goals and filters of newly committed schemes commit 7d390b53067ef745e2d9bee5a9683df4c96b80a0 upstream. damon_commit_schemes() ignores quota goals and filters of the newly committed schemes. This makes users confused about the behaviors. Correctly handle those inputs.
