Subject: [PATCH 0/3] nfsd: plug some filecache refcount leaks

Youzhong Yang sent an email to the list (along with some draft patches)
that indicated some nfsd_file refcount leaks. I went crawling over the
filecache code (again) and found a couple of places where we didn't put
references when we should. I'm not sure if it'll fix the problem they
reported, but they are bugs.

Plus, let's start counting nfsd_file allocations. The last patch adds
support for this.
