+++ This bug was initially created as a clone of Bug #1489043 +++

The number of bytes specified in version 3.7 or later is incorrect. Therefore, only 7711 quota settings can be registered.

"quota.conf corrupted"

Additional info:

Line 927

while ((bytes_read = sys_read (src_fd, (void *)&buf, entry_sz)) > 0) {
    if (bytes_read % 16 != 0) {

------------- quota: fixes issue in quota.conf when setting large number of limits

Problem: It was not possible to configure more than 7712 quota limits.
This was because a stack buffer of size 131072 was used to read from
quota.conf file. In the new format of quota.conf file each gfid entry
takes 17bytes (16byte gfid + 1 byte type). So, the buf_size was not a
multiple of gfid entry size and as per code this was considered as

Solution: make buf size multiple of gfid entry size
