Merge tag 'printk-for-5.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux
Pull printk fixes from Petr Mladek:
"Make the global console_sem available for CPU that is handling panic()
or shutdown.
This is an old problem when an existing console lock owner might block
console output, but it became more visible with the kthreads"
* tag 'printk-for-5.19-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux:
printk: Wait for the global console lock when the system is going down
printk: Block console kthreads when direct printing will be required
