Subject: mm/damon/stat: fix memory leak on damon_start() failure in damon_stat_start()
Date: Tue, 31 Mar 2026 18:15:53 +0800
Destroy the DAMON context and reset the global pointer when damon_start() fails. Otherwise, the context allocated by damon_stat_build_ctx() is leaked, and the stale damon_stat_context pointer will be overwritten on the next enable attempt, making the old allocation permanently unreachable.
