Subject: [PATCH v6 23/52] btrfs: handle btrfs_record_root_in_trans failure in start_transaction
Date: Tue, 8 Dec 2020 11:23:30 -0500 [thread overview]
Message-ID: <90766a86c5e5ac96c9494d2f3e8a149fd4719dc4.1607444471.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1607444471.git.josef@toxicpanda.com>
btrfs_record_root_in_trans will return errors in the future, so handle
the error properly in start_transaction.
