From 156baec39732f025dc778e00da95fc10d6e45885 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 7 Dec 2017 09:40:38 -0800 Subject: rcu: Export init_rcu_head() and destroy_rcu_head() to GPL modules Use of init_rcu_head() and destroy_rcu_head() from modules results in the following build-time error with CONFIG_DEBUG_OBJECTS_RCU_HEAD=y: ERROR: "init_rcu_head" [drivers/scsi/scsi_mod.ko] undefined! ERROR: "destroy_rcu_head" [drivers/scsi/scsi_mod.ko] undefined! This commit therefore adds EXPORT_SYMBOL_GPL() for each to allow them to be used by GPL-licensed kernel modules.
