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, -Andre
