From 561190e3b3db372403fb6a327b0121b4cae1b87e Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 30 Mar 2011 09:10:44 -0700 Subject: rcu: mark rcutorture boosting callback as being on-stack The CONFIG_DEBUG_OBJECTS_RCU_HEAD facility requires that on-stack RCU callbacks be flagged explicitly to debug-objects using the init_rcu_head_on_stack() and destroy_rcu_head_on_stack() functions. This commit applies those functions to the rcutorture code that tests RCU priority boosting. Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.
