Bug description:  PHP reports wrong total and free space for NFS-mounted 
filesystems on RedHat

Description:
------------
disk_total_space, disk_free_space reports wrong total and free space for
NFS-mounted filesystems on RedHat Linux.

This bug seems to be the related to #39520, if not the same. #39520 has
been rated as 'bogus' which I think is a mistake. Please re-consider.

The bug shows on RedHat Linux, but not SuSE Linux. This might ultimately
be considered as a RedHat bug or of the libraries used there, but other
commands (df) that use the statfs system call show the correct file system
size / free space. 

It may be argued (like in #39520) that the wrong block size parameter is
used to calculate total or free disk space. strace df -h shows RedHat and
SuSE report different f_frsize, but same f_bsize on the same NFS share, but
df reports the correct size on both.

Reproduce code:
---------------
Test: Mount a NFS share on a RedHat system and on a SuSE Linux system.

1) RedHat 2.6.9-34.EL, 32-bit
[EMAIL PROTECTED] /]# mount -t nfs 10.20.0.178:/dot/oracle_dump /mnt
[EMAIL PROTECTED] /]# df -h
Filesystem                   Size Used Avail Use% Mounted on
...
10.20.0.178:/dot/oracle_dump 280G 125G 156G 45% /mnt
[EMAIL PROTECTED] /]# /dot/dc/bin/php/bin/php -r
'echo_number_format(disk_total_space("/mnt")) . "\n";'
37,512,204,288    ==> Wrong size, seems to be real size / 8

2) SuSE Linux 9.3 32-bit
suse:/ # mount -t nfs 10.20.0.178:/dot/oracle_dump /mnt
suse:/ # df -h
Filesystem                   Size Used Avail Use% Mounted on
...
10.20.0.178:/dot/oracle_dump 280G 125G 156G 45% /mnt
suse:/ # php -r 'echo number_format(disk_total_space("/mnt")) . "\n";'
300,097,634,304    ==> Correct.


Expected result:
----------------
I would expect the result to be 300G on both systems.

Actual result:
--------------
Reports 300G on SuSE Linux, around 35G only on RedHat.
