I think it should be cleaner to define STRUCT_file_clone_range in
linux-user/syscall_types.h with STRUCT() macro, and then to use it:
STRUCT(file_clone_range,
TYPE_LONGLONG, /* src_fd */
TYPE_ULONGLONG, /* src_offset */
TYPE_ULONGLONG, /* src_length */
TYPE_ULONGLONG) /* dest_offset */
IOCTL(FICLONERANGE, IOC_W, MK_PTR(MK_STRUCT(STRUCT_file_clone_range)))
