From 9a93dc092c6951cdfa6e05c3885a006e5e56d7d3 Mon Sep 17 00:00:00 2001 From: Derrell Lipman Date: Sun, 10 May 2009 22:58:12 -0400 Subject: Optimize smb_thread_once usage by not calling it if known already called - The macro SMB_THREAD_ONCE now tests whether the "once" variable is already set, and if so avoids calling smb_thread_once().
