From c68ca7b72017f8f52e7aed0d2a6ecfaede133b6b Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Tue, 11 May 2010 14:30:12 +0000 Subject: tipc: add tipc_ prefix to fcns targeted for un-inlining These functions have enough code in them such that they seem like sensible targets for un-inlining. Prior to doing that, this adds the tipc_ prefix to the functions, so that in the event of a panic dump or similar, the subsystem from which the functions come from is immediately clear.
