From cc05d5d94bda595e66cf68a90b313baff5dc20ab Mon Sep 17 00:00:00 2001 From: Swaraj Gaikwad Date: Thu, 11 Dec 2025 03:27:22 +0000 Subject: [PATCH] mm/damon/sysfs-schemes: remove outdated TODO in target_nid_store() The TODO comment in target_nid_store() suggested adding range validation for target_nid. As discussed in [1], the current behavior of accepting any integer value is intentional. DAMON sysfs aims to remain flexible, including supporting users who prepare node IDs before future NUMA hotplug events. Because this behavior matches the broader design philosophy of the DAMON sysfs interface, the TODO comment is now misleading. This patch removes the comment without introducing any behavioral change. No functional changes.
