From: Stephen Hemminger <shemminger@...tta.com>
To: David Miller <davem@...emloft.net>, paul.gortmaker@...driver.com
Cc: nhorman@...driver.com, netdev@...r.kernel.org,

Subject: [PATCH net-next] 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.
