Subject: [PATCH 08/14] mm/damon/core: do not call ops.cleanup() when destroying targets
Date: Sat, 12 Jul 2025 12:50:10 -0700	[thread overview]
Message-ID: <20250712195016.151108-9-sj@kernel.org> (raw)
In-Reply-To: <20250712195016.151108-1-sj@kernel.org>

damon_operations.cleanup() is documented to be called for kdamond
termination, but also being called for targets destruction, which is
done for any damon_ctx destruction.  Nobody is using the callback for
now, though.  Remove the cleanup() call under the destruction.
