Because you need to umount /proc/fs/nfsd.
Note: you'll also need to restart rpc.idmapd.
Try the following:
service nfs start # which load everything that's needed
service nfs stop
service rpcidmapd stop
umount /proc/fs/nfsd
rmmod nfsd
Then to (safely) reinstall the module
insmod /tmp/nfsd.ko
mount -t nfsd nfsd /proc/fs/nfsd
service nfs start (which also will start rpcidmapd on FC boxes)
steved.

I compile kernel 2.6.11.10 and configure both nfs client and server as
kernel modules. But after I reboot the machine and did
"/etc/init.d/nfs start", the nfsd module is inserted. But when I tried
to rmmod this module either with "/etc/init.d/nfs stop" or "umount
/proc/fs/nfsd; rmmod nfsd", the nfsd reference count is always 1 and
cannot be removed. Why?
Thanks in advance for your kind help!

Please discard the previous message.
I just noticed that something was wrong in the nfsd implementation
(slightly modified by me). After I fixed the problem, I can rmmod nfsd
now.
Sorry for the confusion.
