The problem (as Trod said) is that the cache only gets flushed if
find_fh_dentry(...) is called. So is the server is not accessed
then the cache never gets flushed.

I see three ways to solve this problem:

1. have a user daemon make a system call periodically.
2. have a user daemon send a signal periodically
3. have the kernel call a subroutine periodically.

To me 3. is the best solution, but I don't know how to set
an alarm in the kernel.

I'll keep looking.
