From ffc2e518c91942b7ed45fb0ab7deba1ba0c8594a Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 5 Dec 2006 16:35:11 -0500 Subject: [PATCH] SUNRPC: Allocate a private data area for socket-specific rpc_xprt fields When setting up a new transport instance, allocate enough memory for an rpc_xprt and a private area. As part of the same memory allocation, it will be easy to find one, given a pointer to the other.
