Subject: [RFC PATCH v2 0/2] samples/damon/mtier: handle damon_{start,stop}() failures
Date: Tue, 9 Jun 2026 07:21:15 -0700 [thread overview]
Message-ID: <20260609142119.68120-1-sj@kernel.org> (raw)
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@kernel.org
- Add damon_stop() failure handling fix to the series.
