      printk: flush continuation lines immediately to console · 084681d1
      Kay Sievers 提交于
      Continuation lines are buffered internally, intended to merge the
      chunked printk()s into a single record, and to isolate potentially
      racy continuation users from usual terminated line users.
      
      This though, has the effect that partial lines are not printed to
      the console in the moment they are emitted. In case the kernel
      crashes in the meantime, the potentially interesting printed
      information would never reach the consoles.
      
      Here we share the continuation buffer with the console copy logic,
      and partial lines are always immediately flushed to the available
      consoles. They are still buffered internally to improve the
      readability and integrity of the messages and minimize the amount
      of needed record headers to store.
