> This series overhauls the NFSD filecache, a cache of server-side
> "struct file" objects recently used by NFS clients. The purposes of
> this overhaul are an immediate improvement in cache scalability in
> the number of open files, and preparation for further improvements.
>
> There are three categories of patches in this series:
>
> 1. Add observability of cache operation so we can see what we're
> doing as changes are made to the code.
>
> 2. Improve the scalability of filecache garbage collection,
> addressing several bugs along the way.
>
> 3. Improve the scalability of the filecache hash table by converting
> it to use rhashtable.
>
> The series as it stands survives typical test workloads. Running
> stress-tests like generic/531 is the next step.
