      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.

      printk: fix regression in SYSLOG_ACTION_CLEAR · 4661e356
      Alan Stern 提交于
      Commit 7ff9554b (printk: convert
      byte-buffer to variable-length record buffer) introduced a regression
      by accidentally removing a "break" statement from inside the big
      switch in printk's do_syslog().  The symptom of this bug is that the
      "dmesg -C" command doesn't only clear the kernel's log buffer; it also
      disables console logging.
      
      This patch (as1561) fixes the regression by adding the missing
      "break".

      stable: Allow merging of backports for serious user-visible performance issues · eb3979f6
      Mel Gorman 提交于
      Distribution kernel maintainers routinely backport fixes for users that
      were deemed important but not "something critical" as defined by the
      rules. To users of these kernels they are very serious and failing to fix
      them reduces the value of -stable.
      
      The problem is that the patches fixing these issues are often subtle and
      prone to regressions in other ways and need greater care and attention.
      To combat this, these "serious" backports should have a higher barrier
      to entry.
      
      This patch relaxes the rules to allow a distribution maintainer to merge
      to -stable a backported patch or small series that fixes a "serious"
      user-visible performance issue. They should include additional information on
      the user-visible bug affected and a link to the bugzilla entry if available.
      The same rules about the patch being already in mainline still apply.
