Until then, we get EEXIST, as you handle above. i.e. if I mount with all 3 quota types: # mount -o gquota -o uquota -opquota /dev/pmem0p1 /mnt/test # xfs_quota -x -c off /mnt/test # xfs_quota -x -c off /mnt/test Quota already off. # xfs_quota -x -c "off -g" /mnt/test # xfs_quota -x -c "off -g" /mnt/test Quota already off. # xfs_quota -x -c "off -p" /mnt/test # xfs_quota -x -c "off -p" /mnt/test XFS_QUOTAOFF: Function not implemented we can see the difference. So this might need a bit more logic (and probably some kernel code reading?) to make things consistent. -Eric

Make the error messages for rudimentary xfs_quota commands (off, enable, disable) more user friendly, instead of the terse sys error outputs.
