From e18190b7e97e9db6546390e6e0ceddae606892b2 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Mon, 15 Sep 2025 20:15:49 -0700 Subject: [PATCH] mm/damon/lru_sort: use param_ctx for damon_attrs staging damon_lru_sort_apply_parameters() allocates a new DAMON context, stages user-specified DAMON parameters on it, and commits to running DAMON context at once, using damon_commit_ctx(). The code is, however, directly updating the monitoring attributes of the running context. And the attributes are over-written by later damon_commit_ctx() call. This means that the monitoring attributes parameters are not really working. Fix the wrong use of the parameter context.
