The sysfs code for online targets updating can result in adding more than
expected monigoring targets to the context.  It can result in unexpected amount
of memory consumption and monitoring overhead.  This patchset fixes the issue
(patch 1), and add a kunit test for avoiding similar bug of future (patch 2).

SeongJae Park (2):
  mm/damon/sysfs: remove requested targets when online-commit inputs
  mm/damon/sysfs-test: add a unit test for damon_sysfs_set_targets()
