Subject: [PATCH v2 06/10] drm/ttm: move zombie handling into ttm_bo_evict
Date: Mon, 06 Jul 2026 12:07:48 +0200 [thread overview]
Message-ID: <20260706-ttm_2_drm_exec-v2-6-4bf6bfc0d320@pixelcluster.dev> (raw)
In-Reply-To: <20260706-ttm_2_drm_exec-v2-0-4bf6bfc0d320@pixelcluster.dev>
Both callers do the same thing, so we can trivially unify that.
