From 01896f7e0a122e8f20082e24f6f9a340034b9c01 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Sun, 18 Aug 2013 12:14:32 -0700 Subject: rcu: Convert local functions to static The rcu_cpu_stall_timeout kernel parameter, the rcu_dynticks per-CPU variable, and the rcu_gp_fqs() function are used only locally. This commit therefore marks them as static. Reported-by: kbuild test robot Signed-off-by: Paul E.
