If past experience with 2.0 is of any value, nfs_delete_inode is called too
early in the process so it's not the right place to totally destroy the
inode. Some of the code in that function should probably go to nfs_clear_inode
(which 2.0 didn't have unfortunately).
If I get some time this coming week, I might have a look at the problem.
BTW, performance tweak or not, NFS (at least over UDP) is basically unusable
right now, I get something like 10k/s write & read performance to a Solaris
server. NFS/TCP is much better, but it has other problems, although your last
patch is definitely a major step in the right direction.
