Description of problem:

After running up2date recently and upgrading the kernel to
2.4.20-13.7, quotas stopped working.

When trying to turn quotas on, this produces an error:
#> quotaon -auv
quotaon: using /export/home/quota.user on /dev/sda5: Invalid argument
quotaon: using /export/home1/quota.user on /dev/sdb1: Invalid argument
quotaon: using /export/home2/quota.user on /dev/sdb3: Invalid argument
#> uname -a
Linux clamp.thebook.com 2.4.20-13.7smp #1 SMP Mon May 12 12:31:27 EDT 2003 i686 
unknown


Rebooting to the previous kernel (2.4.18-27.7.xsmp) the quotas work
fine.
#> quotaon -auv
/dev/sda5 [/export/home]: user quotas turned on
/dev/sdb1 [/export/home1]: user quotas turned on
/dev/sdb3 [/export/home2]: user quotas turned on
#> uname -a 
Linux clamp.thebook.com 2.4.18-27.7.xsmp #1 SMP Fri Mar 14 05:52:30 EST 2003 
i686 unknown
