Subject: [PATCH 11/11] samples/damon/prcl: do not stop DAMON for damon_call() failure
Date: Mon, 6 Jul 2026 07:06:26 -0700 [thread overview]
Message-ID: <20260706140628.87414-12-sj@kernel.org> (raw)
In-Reply-To: <20260706140628.87414-1-sj@kernel.org>
damon_call() failure was causing the context to be stopped, but
asynchronously by the kdamond thread. To handle the race, the caller
had to stop the context. damon_call() is updated to do the stop on its
own. Remove the damon_stop() call from the damon_call() error handling.
