From 642ee6b209c2f4c20fe0a7ed36b429c470162eae Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 9 Apr 2019 11:46:17 -0400 Subject: SUNRPC: Allow further customisation of RPC program registration Add a callback to allow customisation of the rpcbind registration. When clients have the ability to turn on and off version support, we want to allow them to also prevent registration of those versions with the rpc portmapper.
