Subject: [PATCH 2/2] drm/amdgpu: add shared fdinfo stats
Date: Thu, 7 Dec 2023 13:02:25 -0500	[thread overview]
Message-ID: <20231207180225.439482-3-alexander.deucher@amd.com> (raw)
In-Reply-To: <20231207180225.439482-1-alexander.deucher@amd.com>

Add shared stats.  Useful for seeing shared memory.

v2: take dma-buf into account as well
