From dffd06a7566b379be13a831b27a55bf5b0a7dea5 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 23 Jan 2017 11:55:43 -0800 Subject: rcu: Semicolon inside RCU_TRACE() for rcu.h The current use of "RCU_TRACE(statement);" can cause odd bugs, especially where "statement" is a local-variable declaration, as it can leave a misplaced ";" in the source code. This commit therefore converts these to "RCU_TRACE(statement;)", which avoids the misplaced ";". Reported-by: Josh Triplett Signed-off-by: Paul E.
