In-Reply-To: <20261026134740.149027-1-sj@kernel.org>
> Patch series "mm/damon: move zero damos quota target_value handling to the
> core layer".
>
> Having zero DAMOS quota target value can cause division by zero. DAMON
> API callers are checking the target value parameters to avoid that. It is
> easy to make mistakes in some of the multiple API callers. Move that to
> the core layer.
>
> Patch 1 adds the corner case handling into the core layer DAMON parameters
> validation logic. Patches 2 and 3 remove no more needed DAMON API callers
> side handling of the corner case in DAMON_LRU_SORT and DMON_SAMPLIE_MTIER,
> respectively.
