So my quota tests (219 and 232) still fail (zero output from repquota)
and I realized 2 things:

1. they don't fail with kernel 2.6.38 (Ubuntu 11.4 shipped kernel)

2. what seems to fail is quotaon:

amir@...ab:~/xfstests$ sudo quotaon /mnt/test/scratch
quotaon: using /mnt/test/scratch/aquota.user on /dev/sda8
[/mnt/test/scratch]: No such process
quotaon: Quota format not supported in kernel.

Which also explains why quotaoff was called without quotaon in my
original bug report.

amir@...ab:~/xfstests$ quotaon -V
Quota utilities version 4.00-pre1.
Compiled with: USE_LDAP_MAIL_LOOKUP EXT2_DIRECT HOSTS_ACCESS
ALT_FORMAT RPC RPC_SETQUOTA BSD_BEHAVIOUR
Bugs to jack@...e.cz

Any suggestions?

Amir.
