From 1bca8cf1a2c3c6683b12ad28a3e826ca7a834978 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 12 Jun 2012 09:40:38 -0700 Subject: rcu: Remove unneeded __rcu_process_callbacks() argument With the advent of __this_cpu_ptr(), it is no longer necessary to pass both the rcu_state and rcu_data structures into __rcu_process_callbacks(). This commit therefore computes the rcu_data pointer from the rcu_state pointer within __rcu_process_callbacks() so that callers can pass in only the pointer to the rcu_state structure. This paves the way for linking the rcu_state structures together and iterating over them. Signed-off-by: Paul E.
