[just documenting this for posterity or in case someone wants to fix it.] In drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c, one can find both struct amdgpu_vm_tlb_seq_cb {...}; and static void amdgpu_vm_tlb_seq_cb(...) Of course C has no problem with this, but kernel-doc reports: drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c:833: WARNING: Duplicate C declaration, also defined at gpu/amdgpu/driver-core:115. And of course, if the name of one of them is changed, kernel-doc is all happy... not that I am suggesting that one of them should be changed. I just want to make people aware of this. (or maybe people are already aware of this?) -- ~Randy
