Appended is a patch which allows to include NFS filesystem
as a module. The symbol exit_mm is not resolved otherwise.
(I don't know if it is the correct place to export that symbol.)

By the way, when nfs is AUTOLOADED by mounting a nfs volume,
the use count for nfs (output of lsmod) is set to 5
(1 for the filesystem and 4 for four nfsiod daemons).
Unmounting the nfs volume decrements the use count by 1, but it
remains 4 due to the 4 daemons, which are not killed.
So the nfs module is NOT AUTOREMOVED BY KERNELD. Is it
possible to change that behaviour, eg by killing the nfsiods with
a call to kill_proc in cleanup_module?
