[RFC PATCH v2 0/2] samples/damon/mtier: handle damon_{start,stop}() failures

From: SeongJae Park

Date: Tue Jun 09 2026 - 10:30:48 EST


DAMON sample module mtier is not correctly handling failures from
damon_start() and damon_stop(). As a result, it can leak memory,
disrupt next DAMON operations, and dereference freed and random memory.
Fix those.

Changes from RFC v1
- RFC v1: https://lore.kernel.org/20260609005443.2122-1-sj@xxxxxxxxxx
- Add damon_stop() failure handling fix to the series.

samples/damon/mtier: handle damon_start() failure
samples/damon/mtier: handle damon_stop() failure
