The f_spare field within struct compat_statfs is four bytes larger than within the native 31 bit struct statfs. compat_sys_statfs() clears the f_spare field in user space which means that in compat mode four bytes that are behind the user space supplied struct compat_statfs will be corrupted (zeroed). According to Thomas Gleixner's Linux 2.6 history tree this bug is present since v2.5.74 87880da124 "[PATCH] s390: 31 bit compat.". So it get's fixed shortly before its 10th anniversary. Tough luck.
