      pty: fix data loss when stopped (^S/^Q) · 85dfd81d
      Linus Torvalds 提交于
      Commit d945cb9c ("pty: Rework the pty layer to use the normal buffering
      logic") dropped the test for 'tty->stopped' in pty_write_room(), which
      then causes the n_tty line discipline thing to not throttle the data
      properly when the tty is stopped.
      
      So instead of pausing the write due to the tty being stopped, the ldisc
      layer would go ahead and push it down to the pty.  The pty write()
      routine would then refuse to take the data (because it _did_ check
      'stopped'), and the data wouldn't actually be written.
      
      This whole stopped test should eventually be moved into the tty ldisc
      layer rather than have low-level tty drivers care about these things,
      but right now the fix is to just re-instate the missing pty 'stopped'
      handling.
