Howto compile nfsd as module ?

[adrianp]

Following the module compile HOWTO works for compiling nsfd but when loading the module a couple of symbols are missing (depmod -a has been run) :-

nfsd: Unknown symbol find_exported_dentry
nfsd: Unknown symbol export_op_default

These come from exportfs which unfortunately isn't enabled in the kernel :-
uname -r : 2.6.12-xenU
zgrep EXPORTFS /proc/config.gz : <nothing>

Trying to "make menuconfig" nfsd as a module in the config gives :-
..
CONFIG_NFSD=m
..
CONFIG_EXPORTFS=y

Ah, so CONFIG_EXPORTFS is compiled in when NFSD is a module but the Unixshell kernel doesn't have EXPORTFS compiled in

Does anyone know a way to solve this ?
