[RFC PATCH v2 0/2] mm/damon: avoid division by zero from damos_quota_score()

[SJ Park]

DAMON_SAMPLE_MTIER and DAMON_LRU_SORT allow the user to trigger division
by zero in damos_quota_score().  Avoid it by adding parameters
validation checks.

Changes from RFC
- RFC: https://lore.kernel.org/20260801211315.2456-1-sj@xxxxxxxxxx
- Add a fix for DAMON_LRU_SORT.

SJ Park (2):
  samples/damon/mtier: error out for zero quota goal target values
  mm/damon/lru_sort: error out for >10000 active_mem_bp
