Subject: [PATCH 0/2] nfsd: use threads array as-is in netlink thread set
 interface

The first patch is probably appropriate for stable. It should fix
problems when someone sets the pool_mode to pernode, without userland
sending down a fully-populated thread array.

The second patch just adds a couple of new tracepoints that I ended up
using to track this down.
