Subject: [PATCH v5 49/52] btrfs: do not WARN_ON() if we can't find the reloc root
Date: Mon, 7 Dec 2020 08:57:41 -0500 [thread overview]
Message-ID: <efdaeb31364dac5dcc1d35832fbfecc184320b9a.1607349282.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1607349281.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.
