Works either way. Either way--it looks like the bug was introduced with
c526611dd631b2802b6b0221ffb306c5fa25c86c "SUNRPC: Use a cached RPC
client and transport for rpcbind upcalls" and
7402ab19cdd5943c7dd4f3399afe3abda8077ef5 "SUNRPC: Use AF_LOCAL for
rpcbind upcalls"
and should go to stable as well.
(Looks like I said that before but accidentally dropped everyone off the
cc.)
