xfs_quota: Getting back disk space usage of a single directory

[Asfand Yar Qazi <asfand_yar.qazi@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

If I have an XFS mount that contains many directories, each one 
project-quotaed, how can I use xfs_quota to get back the amount of quota 
used by just one directory?
I know I can use xfs_quota -x -c quot -p /blah to get back quota usages 
for all projects in that mount, but I want to get back just one.
Thanks
