Subject: [PATCH 05/21] btrfs: pass root to various extent ref mod functions
Date: Fri, 29 Sep 2017 15:43:49 -0400 [thread overview]
Message-ID: <1506714245-23072-6-git-send-email-jbacik@fb.com> (raw)
In-Reply-To: <1506714245-23072-1-git-send-email-jbacik@fb.com>
We need the actual root for the ref verifier tool to work, so change
these functions to pass the root around instead. This will be used in
a subsequent patch.
