From 64a3030683fab242a1608d7c35766130faffc1c0 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 23 Dec 2009 11:29:19 -0500 Subject: libnsm.a: Move the sm_inter XDR pieces to libnsm.a Clean up: Move the .x file and the generated C source for NSM to libnsm.a, echoing the architecture of mountd and exportfs. This makes the NSM protocol definitions, data types, and XDR routines available to be shared across nfs-utils. This simplifies the addition of other NSM-related code (for example for testing or providing clustering support), and also provides public data type definitions that can be used to make sense of the contents of statd's on-disk database. Because sim_sm_inter.x still resides in utils/statd, I've left some rpcgen build magic in utils/statd/Makefile.am. This is an internal organization change only. This patch should not affect code behavior in any way.
