How did you add ocf to your kernel ?

Did you apply the "big" 2.6.22 patch or did you integrate it by hand ?

Check that all the parts of the patch:

	ocf/patches/linux-2.6.22-ocf.patch

have been applied.  Particularly the export of sys_dup.

What were the errors ?

See how we go with the above,  but we'll sort it out for sure ;-)
