Subject: [PATCH 3/3] dma-fence: Init and enable signalling can use the fast path tracepoint
Date: Mon, 13 Apr 2026 11:05:26 +0100	[thread overview]
Message-ID: <20260413100526.15729-3-tvrtko.ursulin@igalia.com> (raw)
In-Reply-To: <20260413100526.15729-1-tvrtko.ursulin@igalia.com>

From dma_fence_init (cannot signal yet) and dma_fence_enable_signaling
(fence->lock and rcu_read_lock held, ops checked manually), it is safe to
use the marginally faster tracepoint class.
