[RFC PATCH v3 0/4] samples/damon: handle damon_{start,stop}() failures
From: SeongJae Park
Date: Tue Jun 09 2026 - 21:20:05 EST
All DAMON sample modules are not correctly handling failures from
damon_start(). Among those, mtier also has an additional problem for
handling of damon_stop() failures. As a result, memory leaks, next
DAMON operation disruptions, and use-after-free can happen. Fix those.
Changes from RFC v2
- RFC v2: https://lore.kernel.org/20260609142119.68120-1-sj@xxxxxxxxxx
- Add damon_start() failure handling fix for wsse and prcl.
