The build errors here seem to stem from a bunch of places in the source code where the extents type is left as default (uint32_t) or defined incorrectly. The previous mdspan implementation was willing to implicitly convert something like raft::make_device_matrix_view<const int64_t, uint64_t> to raft::make_device_matrix_view<const int64_t, int64_t>, unsafely casting uint64 to int64 in the extents type. The CCCL mdspan does not allow that. I am iterating through build errors to ensure that we have extent types properly defined.
