From 791875d16e2f6e2e5b90328ccac643f512ac76c4 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 3 May 2017 11:06:05 -0700 Subject: rcu: Eliminate the unused __rcu_is_watching() function The __rcu_is_watching() function is currently not used, aside from to implement the rcu_is_watching() function. This commit therefore eliminates __rcu_is_watching(), which has the beneficial side-effect of shrinking include/linux/rcupdate.h a bit. Reported-by: Ingo Molnar Signed-off-by: Paul E.
