From 7b2e6011f150c42235c4a541d20cf6891afe878a Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 8 Oct 2012 10:54:03 -0700 Subject: rcu: Rename ->onofflock to ->orphan_lock The ->onofflock field in the rcu_state structure at one time synchronized CPU-hotplug operations for RCU. However, its scope has decreased over time so that it now only protects the lists of orphaned RCU callbacks. This commit therefore renames it to ->orphan_lock to reflect its current use.
