From 2214b5de0a93f51d145ff22a98257868790e7abc Mon Sep 17 00:00:00 2001 From: Bijan Tabatabai Date: Tue, 8 Jul 2025 19:47:29 -0500 Subject: [PATCH] mm/damon/core: commit damos->target_nid commit 579bd5006fe7f4a7abb32da0160d376476cab67d upstream. When committing new scheme parameters from the sysfs, the target_nid field of the damos struct would not be copied. This would result in the target_nid field to retain its original value, despite being updated in the sysfs interface. This patch fixes this issue by copying target_nid in damos_commit().
