Ok, got it.

Again these are just internal to glibc, the kernel just uses fixed width
types in

typedef struct {
        int     val[2];
} __kernel_fsid_t;

struct statfs64 {
        __u32 f_type;
        __u32 f_bsize;
        __u64 f_blocks; 
        __u64 f_bfree;  
        __u64 f_bavail;
        __u64 f_files;
        __u64 f_ffree;
        __kernel_fsid_t f_fsid;
        __u32 f_namelen;
        __u32 f_frsize;
        __u32 f_flags;
        __u32 f_spare[4];
};

so we need to be careful to define them in glibc to match the kernel
types, but the kernel definition doesn't need changes.
