[RFC PATCH 0/2] mm/damon: void divide-by-zero in DAMON module's parameters application

[Quanmin Yan]

DAMON's RECLAIM or LRU_SORT modules perform no validation on
user-configured parameters during application, which may lead
to division-by-zero errors.

Avoid the divide-by-zero by adding validation checks when DAMON
modules attempt to apply the parameters.

Quanmin Yan (2):
  mm/damon/lru_sort: avoid divide-by-zero in
    damon_lru_sort_apply_parameters()
  mm/damon/reclaim: avoid divide-by-zero in
    damon_reclaim_apply_parameters()
