From 11a147013e39ff4cb031395cb78a9d307c4799cd Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Wed, 4 Oct 2006 02:17:16 -0700 Subject: [PATCH] rcu: add rcu_bh_sync torture type to rcutorture Use the newly-generic synchronous deferred free function to implement torture testing for rcu_bh using synchronize_rcu_bh rather than the asynchronous call_rcu_bh.
