    jbd2: track more dependencies on transaction commit · 1eaa566d
    Jan Kara authored
    So far we were tracking only dependency on transaction commit due to
    starting a new handle (which may require commit to start a new
    transaction). Now add tracking also for other cases where we wait for
    transaction commit. This way lockdep can catch deadlocks e. g. because we
    call jbd2_journal_stop() for a synchronous handle with some locks held
    which rank below transaction start.
