Subject: [PATCH drm-misc-next v4 1/8] drm/gpuvm: rename struct drm_gpuva_manager to struct drm_gpuvm
Date:   Wed, 20 Sep 2023 16:42:34 +0200
Message-ID: <20230920144343.64830-2-dakr@redhat.com>
In-Reply-To: <20230920144343.64830-1-dakr@redhat.com>

Precedence: bulk

Rename struct drm_gpuva_manager to struct drm_gpuvm including
corresponding functions. This way the GPUVA manager's structures align
very well with the documentation of VM_BIND [1] and VM_BIND locking [2].

It also provides a better foundation for the naming of data structures
and functions introduced for implementing a common dma-resv per GPU-VM
including tracking of external and evicted objects in subsequent
patches.
