Subject: [GIT PULL] printk fixups for 5.19-rc3

Hi Linus,

please pull two printk fixups from

  git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-5.19-rc3

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

- Make the global console_sem available for CPU that is handling
  panic() or shutdown. It is an old problem when an existing
  console lock owner might block console output. It became
  more visible with the kthreads.

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

I am sorry for the late pull request. I wanted to give it at
least two days in linux-next.

----------------------------------------------------------------
Petr Mladek (3):
      printk: Block console kthreads when direct printing will be required
      printk: Wait for the global console lock when the system is going down
      Merge branch 'rework/kthreads' into for-linus
