    [PATCH] JBD: remove jh_splice_lock · 6fe2ab38
    Andrew Morton authored
    This was a strange spinlock which was designed to prevent another CPU from
    ripping a buffer's journal_head away while this CPU was inspecting its state.
    
    Really, we don't need it - we can inspect that state directly from bh->b_state.
    
    So kill it off, along with a few things which used it which are themselves
    not actually used any more.
