Subject: [PATCH 05/13] btrfs: do not WARN_ON() if we can't find the reloc root
Date: Wed, 16 Dec 2020 11:22:09 -0500 [thread overview]
Message-ID: <d11a0c1770a96bdf382cc3f41eb71fb790650aa5.1608135557.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1608135557.git.josef@toxicpanda.com>
Any number of things could have gone wrong, like ENOMEM or EIO, so don't
WARN_ON() if we're unable to find the reloc root in the backref code.
