Update.
2003-06-24 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/fstatfs64.c (__fstatfs64): Add support for the fstatfs64 syscall. * sysdeps/unix/sysv/linux/statfs64.c (__statfs64): Add support for the statfs64 syscall. * sysdeps/unix/sysv/linux/kernel-features.h: Define __ASSUME_STATFS64 appropriately. * sysdeps/unix/sysv/linux/internal_statvfs.c: Use f_frsize field from statfs structure if it has been filled in. * sysdeps/unix/sysv/linux/bits/statfs.h (struct statfs): Add f_frsize field. (struct statfs64): Likewise. * sysdeps/unix/sysv/linux/alpha/bits/statfs.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/statfs.h: Likewise. instead of __libc_cleanup_region_*.
