I have this patch now running on a

CPU: Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz (3001.18-MHz 686-class CPU)

machine. I have attached two 10k SCSI drives to an AIC7902
controller. These two drives have quotas enabled and are
constantly copying 77GB of data stored in ~210000 files to
each other. I use about 75 different user and group IDs with
these files.

I haven't had any problem the last 6 hours. The machine runs
rocksolid and the quota values are correct. So, from my point
of view I'd say that the patch works great!

Thanks a lot for the nice work,
