Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/amd/amdgpu/amdgpu_object.c: In function 'amdgpu_bo_release_notify':
drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:1245:28: error: 'struct ttm_buffer_object' has no member named 'resv'
reservation_object_lock(bo->resv, NULL);
^~
drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:1247:47: error: 'struct ttm_buffer_object' has no member named 'resv'
r = amdgpu_fill_buffer(abo, AMDGPU_POISON, bo->resv, &fence);
^~
drivers/gpu/drm/amd/amdgpu/amdgpu_object.c:1253:30: error: 'struct ttm_buffer_object' has no member named 'resv'
reservation_object_unlock(bo->resv);
^~

Caused by commit

5a5011a72489 ("drm/amdgpu: switch driver from bo->resv to bo->base.resv")

interacting with commit

ab2f7a5c18b5 ("drm/amdgpu: Implement VRAM wipe on release")

from the amdgpu tree.

I have added the following patch for today:
