Summary: Failover hangs if root filesystem module unavailable

Initial Comment:
Well, duh!

If the root filesystem is compiled as a module, and not loaded on the failover node then failover hangs.  Pretty obvious realy.

(cfs_root_failover calls do_kern_mount which calls get_fs_type which is forced to call request_module - result hang).

However there is nothing to force the loading of the root filesystem driver on the failover node.

A simple hack is to add it to the modules loaded by the ramdisk.

A cleaner way would to be to load it in cfs_setroot, or rather in the ssi kernel function called by cfs_setroot.
