    UBIFS: synchronize write-buffer before switching to the next bud · cb14a184
    Artem Bityutskiy authored
    Currently when UBIFS fills up the current bud (which is the last in the journal
    head) and switches to the next bud, it first writes the log reference node for
    the next bud and only after this synchronizes the write-buffer of the previous
    bud. This is not a big deal, but an unclean power cut may lead to a situation
    when we have corruption in a next-to-last bud, although it is much more logical
    that we have to have corruption only in the last bud.
    
    This patch also removes write-buffer synchronization from
    'ubifs_wbuf_seek_nolock()' because this is not needed anymore (we synchronize
    the write-buffer explicitly everywhere now) and also because this is just
    prone to various errors.
