    [PATCH] md: merge md_enter_safemode into md_check_recovery · fca4d848
    NeilBrown authored
    md_enter_safemode checks if it is time to mark the md superblock as 'clean'.
    i.e.  if all writes have completed and a suitable delay has passed.
    This is currently called from md_handle_safemode which in-turn is called
    (almost) every time md_check_recovery is called, and from the end of
    md_do_sync which causes the mddev->thread to run, which will always call
    md_check_recovery as well.
    So it doesn't need to be a separate function and fits quite well into
    The "almost" is because multipathd calls md_check_recovery but not
    md_handle_safemode.  This is OK because the code from md_enter_safemode is a
    no-op if mddev->safemode == 0, which it always is for a multipathd (providing
    we don't allow it to be set to 2 on a signal...)
