From f1e3c289498f26d98b65ddaae0cd892c98a6ce84 Mon Sep 17 00:00:00 2001 From: Sasha Levin Date: Wed, 11 Jun 2014 12:00:25 -0400 Subject: btrfs: prevent RCU warning when dereferencing radix tree slot Mark the dereference as protected by lock. Not doing so triggers an RCU warning since the radix tree assumed that RCU is in use.
