Hi, Charles. I've been testing this nfs patch a bit, and I have one
problem in my setup. This might be related to other parts than
yaffs2, but then again, it could be a yaffs bug.

When I export a yaffs2 filesystem with the kernel-space nfs daemon, I
cannot seem to umount the filesystem, even though rpc.nfsd and friends
have been terminated.

I can see an [nfsd] process (i.e. kernel thread), which I believe
might be the culprit. No other processes have any files on my file
system open, no other processes have /proc/pid/{cwd,root} pointing to
the yaffs mount point.

Have you tested this bit? It seems like some kernel-side resources
might not be properly released when we unexport the file system.
