Description of problem:
I upgraded my kernel RPMS via Red Hat network to kernel-2.4.20-13.7

Now it will not enable quota management and when you try to use the
quotaon/quotaoff commands you get the error;

- quotaon: using /home/quota.user on /dev/sda2: Invalid argument

However in all previous 7.3 kernels the quota file has been called aquota.user
and thats what I've used.  I tried making a quota.user file for this new kernel
and it still gives the same error when the quotaon command is issued.

Booting into an previous kernel (ie kernel-2.4.18-27.7.x) fixes the problem. 
However seeing the new buggy version is a security release I'd rather not do this.

I have had this problem on multiple production 7.3 machines.  One of which is
using the SMP kernel.  The SMP version also would not mount my  partitions as
read/write with the "defaults" option specified in /etc/fstab.  It would if I
specified "defaults,rw,usrquota", however this is still a bug as the default
should be read/write.  Perhaps this should be another bug report.

Version-Release number of selected component (if applicable):
kernel-2.4.20-13.7

How reproducible:
Always

Steps to Reproduce:
1. Boot into affected kernel
2. add usrquota option to /etc/fstab
3. mount -o remount /home
4. touch /home/aquota.user
5. checkquota /home
6. quotaon /home

Once this is done it will also produce the error when it tried to start quotas
during bootup. The command "dmesg | less" will show the error.

Actual Results:  quotaon: using /home/quota.user on /dev/sda2: Invalid argument

Expected Results:  Quota management should be enabled
