This patch should fix the oops seen by Daire while testing the latest
NFS netfs fscache conversion patches [1][2].  What follows is a detailed
explanation of the analysis, mostly for reference and in case any of
the patch header is unclear.

I can now confirm that this does indeed fix the issue I was hitting -
it has been over 4 days and I have not seen the crash that I was
reliably reproducing at least once a day.

Many thanks for tracking this down Dave.

I will try to switch over to the v2 patch sometime this week but I
don't expect a change in functionality. The important thing is you
found the place where it was going wrong and why.
