From 0c2ac7d4f08d330dc5b092b4beba9ef88602d369 Mon Sep 17 00:00:00 2001 From: Madhuparna Bhowmik Date: Tue, 25 Feb 2020 18:47:53 +0530 Subject: Bluetooth: Use list_for_each_entry_rcu() to traverse RCU list in RCU read-side CS In function hci_is_blocked_key() RCU list is traversed with list_for_each_entry() in RCU read-side CS. Use list_for_each_entry_rcu() instead.
