From: Olga Kornievskaia <kolga@xxxxxxxxxx> This patch series adds session trunking discovery and setup. When a client discovers a new file system in addition to probing for existing attributes, it also sends a GETATTR asking for an fs_location attribute. If it receives a non-zero length reply, it will iterate thru the response and, for each server location, it will establish a connection (of the same type as the existing RPC transport), send an EXCHANGE_ID, and test for session trunking. If the trunking test succeeds, the transport is added to an existing set of transports for this server.
