From 4a68179d38874c37be2802442a71b847f5d1a2a9 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 22 Aug 2006 20:06:15 -0400 Subject: SUNRPC: Make RPC portmapper use per-transport storage Move connection and bind state that was maintained in the rpc_clnt structure to the rpc_xprt structure. This will allow the creation of a clean API for plugging in different types of bind mechanisms. This brings improvements such as the elimination of a single spin lock to control serialization for all in-kernel RPC binding. A set of per-xprt bitops is used to serialize tasks during RPC binding, just like it now works for making RPC transport connections. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked. Probably need to rig a server where certain services aren't running, or that returns an error for some typical operation.
