Which recent changes?  Something in NFS or something in the VFS/MM?
Did you even think about asking a wider audience than the NFS mailing
list?  I only happened to notice this while I was looking for something
else, otherwise I would never have seen it.  The responses from other
people to your patches were right; you're trying to do this all wrong.

Let's start out with a bug report instead of a solution.  What changed
and when?
