From dc9492c14c758639d7b2468d4ed3c77e785c1a35 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 14 Feb 2020 16:11:44 -0500 Subject: btrfs: hold a ref on the root on the dead roots list At the point we add a root to the dead roots list we have no open inodes for that root, so we need to hold a ref on that root to keep it from disappearing.
