Prev: [PATCH RFC tip/core/rcu 02/11] rcu head introduce rcu head init on stack
Next: [PATCH RFC tip/core/rcu 06/11] staging: remove all rcu head initializations
From: Paul E. McKenney on 11 May 2010 19:40 Remove all rcu head inits. We don't care about the RCU head state before passing it to call_rcu() anyway. Only leave the "on_stack" variants so debugobjects can keep track of objects on stack. Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers(a)efficios.com> Signed-off-by: Paul E.
