            I think - no. The header lnet/klnds/o2iblnd/o2iblnd.h:81 still have "#include <libcfs/libcfs.h>".

            The second approach can be remove dependency on OFED headers from all code except o2iblnd.
            The LNet layer shouldn't refer to anything in the RDMA world directly.
            All OFED dependent code should be localized into o2iblnd.
