Well, this might be attributed to the gpfs share modes and
leases which Samba only makes use of when the gpfs module is
compiled in. This is only relevant though if you have
cross-platform (i.e. CIFS/NFS/local processes) applications
that are also aware of these concepts.

In latest GPFS and Samba we make use the new getrealfilename
call in GPFS which helps you for large directories.
