[PATCH] knfsd: register all RPC programs with portmapper by default
The NFSACL patches introduced support for multiple RPC services listening on
the same transport. However, only the first of these services was registered
with portmapper. This was perfectly fine for nfsacl, as you traditionally do
not want these to show up in a portmapper listing.
The patch below changes the default behavior to always register all services
listening on a given transport, but retains the old behavior for nfsacl
services.
