Subject: [Intel-gfx] [PATCH 4/6] dma-buf: warn about containers in dma_resv object
Date: Fri, 4 Feb 2022 11:04:27 +0100 [thread overview]
Message-ID: <20220204100429.2049-5-christian.koenig@amd.com> (raw)
In-Reply-To: <20220204100429.2049-1-christian.koenig@amd.com>
Drivers should not add containers as shared fences to the dma_resv
object, instead each fence should be added individually.
