[linux-lvm] Local GFS on lvm

This problem happens when you enable the "Set version information on all 
symbols for modules" option under "Loadable module support" when configuring
the kernel.

If you enable the option, you need to apply the attached patch and compile
GFS with the MODVERSIONS=y switch.  (i.e.  cd GFS2/bin;make MODVERSIONS=y)
