'struct hmm_mirror' is not defined without the Kconfig option set, so we cannot include it within another struct:
In file included from drivers/gpu/drm/amd/amdgpu/../amdgpu/amdgpu.h:72: drivers/gpu/drm/amd/amdgpu/../amdgpu/amdgpu_mn.h:69:20: error: field has incomplete type 'struct hmm_mirror' struct hmm_mirror mirror; ^ drivers/gpu/drm/amd/amdgpu/../amdgpu/amdgpu_mn.h:69:9: note: forward declaration of 'struct hmm_mirror' struct hmm_mirror mirror;
Add the #ifdef around it that is also used for all functions operating on it.
