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().
