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.
