I have a fully working solution that uses the dfree option in Samba if
you want.

I am with you here in that a lot of places will be carving a GPFS file
system up with file sets with a quota that are then shared to a group
of users and you want the disk size, and amount free to show up  on the
clients based on the quota for the fileset not the whole file system.

I am really not sure what the issue with the code path for this as it
is 35 lines of C including comments to get the fileset if one exists
for a given path on a GPFS file system. You open a random file on the
path, call gpfs_fcntl and then gpfs_getfilesetid. It's then a simple
call to gpfs_quotactl.
