From 3aac7a8d574285be855450d103a421b8f8ec89d4 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 14 Nov 2012 14:37:29 -0800 Subject: rcu: Fix blimit type for trace_rcu_batch_start() When the type of global variable blimit changed from int to long, the type of the blimit argument of trace_rcu_batch_start() needed to have changed.
