From 31e3c3f6f1f9b154981a0e6620df700463db30ee Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Wed, 13 Oct 2010 13:20:35 +0000 Subject: tipc: cleanup function namespace Do some cleanups of TIPC based on make namespacecheck 1. Don't export unused symbols 2. Eliminate dead code 3. Make functions and variables local 4. Rename buf_acquire to tipc_buf_acquire since it is used in several files Compile tested only. This make break out of tree kernel modules that depend on TIPC routines. Signed-off-by: Stephen Hemminger Acked-by: Jon Maloy Acked-by: Paul Gortmaker Signed-off-by: David S.
