mm/damon/reclaim: avoid divide-by-zero in damon_reclaim_apply_parameters()
Summary
mm/damon/reclaim: avoid divide-by-zero in damon_reclaim_apply_parameters()
Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved:
mm/damon/reclaim: avoid divide-by-zero in damon_reclaim_apply_parameters()
When creating a new scheme of DAMON_RECLAIM, the calculation of
'min_age_region' uses 'aggr_interval' as the divisor, which may lead to
division-by-zero errors. Fix it by directly returning -EINVAL when such a
case occurs.
