Merge tag 'printk-for-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Add KUnit test for the printk ring buffer

 - Fix the check of the maximal record size which is allowed to be
   stored into the printk ring buffer. It prevents corruptions of the
   ring buffer.

   Note that printk() is on the safe side. The messages are limited by
   1kB buffer and are always small enough for the minimal log buffer
   size 4kB, see CONFIG_LOG_BUF_SHIFT definition.

  printk: ringbuffer: Fix data block max size check
