Linus,

please pull the latest printk changes from

  git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-5.15

=====================================

- Optionally, provide an index of possible printk messages via
  <debugfs>/printk/index/. It might be used when monitoring important
  kernel messages on a farm of various hosts. The monitor has to be
  updated when some messages has changed or are not longer available
  by a newly deployed kernel.

- Add printk.console_no_auto_verbose boot parameter. It allows to
  generate crash dump even with slow consoles in a reasonable
  time frame.

- Remove printk_safe buffers. The messages are always stored directly to
  the main logbuffer, even in NMI or recursive context. Also it allows
  to serialize syslog operations by a mutex instead of a spin lock.

- Misc clean up and build fixes.

      lib/test_scanf: Handle n_bits == 0 in random tests
