Subject: mm/damon/core: commit damos->target_nid
Date: Tue, 8 Jul 2025 19:47:29 -0500

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().
