Since the glusterfs vfs module does not operate on a
locally mounted path, but on a "virtual" path starting
at the volume root, some assumptions of the code about
the vfs connect path fail. One example is the shadow_copy2
module which tries to detect the mount point from the
connectpath. In order to circumvent this problem, this
patch forces the "shadow:mountpoint" option to "/", which
skips the mount-point-detection code.
This patch will only have an effect if both the glusterfs
and the shadow_copy2 module are listed in vfs objects
in the right order, i.e. first shadow_copy2, and then
glusterfs.
