This is another one you can't do: all headers in UAPI are exports to userspace and the definitions constitute an ABI. If you simply do a rename, every userspace program that uses the current definition will immediately break on compile. You could add HASH_ALGO_SM3, but you can't remove HASH_ALGO_SM3_256 James
