Subject: [PATCH RFC v3 07/35] mm: cma: Add CMA_RELEASE_{SUCCESS,FAIL} events
Date: Thu, 25 Jan 2024 16:42:28 +0000 [thread overview]
Message-ID: <20240125164256.4147-8-alexandru.elisei@arm.com> (raw)
In-Reply-To: <20240125164256.4147-1-alexandru.elisei@arm.com>
Similar to the two events that relate to CMA allocations, add the
CMA_RELEASE_SUCCESS and CMA_RELEASE_FAIL events that count when CMA pages
are freed.
