s390/uapi: cover statfs padding by growing f_spare
pahole says:
struct compat_statfs64 {
...
u32 f_spare[4]; /* 68 16 */
/* size: 88, cachelines: 1, members: 12 */
/* padding: 4 */
struct statfs {
...
unsigned int f_spare[4]; /* 68 16 */
/* size: 88, cachelines: 1, members: 12 */
/* padding: 4 */
struct statfs64 {
...
unsigned int f_spare[4]; /* 68 16 */
/* size: 88, cachelines: 1, members: 12 */
/* padding: 4 */
One has to keep the existence of padding in mind when working with
these structs. Grow f_spare arrays to 5 in order to simplify things.
