      libata: limit post SRST nsect/lbal wait to ~100ms · e141d999
      Tejun Heo 提交于
      After SRST, libata used to wait for nsect/lbal to be set to 1/1 for
      the slave device.  However, some ATAPI devices don't set nsect/lbal
      after SRST and the wait itself isn't too useful as we're gonna wait
      for !BSY right after that anyway.
      
      Before reset-seq update, nsect/lbal wait failure used to be ignored
      and caused 30sec delay during detection.  After reset-seq, all
      timeouts are considered error conditions making libata fail to detect
      such ATAPI devices.
      
      This patch limits nsect/lbal wait to around 100ms.  This should give
      acceptable behavior to such ATAPI devices while not disturbing the
      heavily used code path too much.
