Subject: [PATCH] drm/panthor: enable fdinfo for memory stats
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Implement drm object's status callback.
Also, we consider a PRIME imported BO to be resident if its matching
dma_buf has an open attachment, which means its backing storage had already
been allocated.
