r12721: GPFS 2.4 on Linux will contain some windows semantics, ie share modes and
oplocks across the cluster. Adapt Samba to it.
The gpfs API is called via libgpfs.so. This code is written with dlopen(), so
that you can compile on a system with gpfs installed and later on run on
systems without gpfs available.
So to actually make Samba call gpfs share mode calls you need to compile with
gpfs.h and libgpfs.so around and set 'gpfs share = yes' on the shares you
export from GPFS.
