thats two different change.
and apart from this:
1) the function declarations were renamed and moved from
lustre/include/linux/libcfs/libcfs.h to drivers/staging/lustre/include/linux/lnet/lib-lnet.h

2) some functions you have changed the coding style. like:
-     rc = libcfs_sock_getaddr(conn->ksnc_sock, 0,
-                              &conn->ksnc_myipaddr, NULL);
+     rc = lnet_sock_getaddr(conn->ksnc_sock, 0, &conn->ksnc_myipaddr, NULL);

regards
sudip
