Subject[GIT PULL] printk for 5.11
Linus,

please pull the latest printk changes from

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-5.11

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

- Finally allow parallel writes and reads into/from the lockless
ringbuffer. But it is not a complete solution. Readers are still
serialized against each other. And nested writes are still
prevented by printk_safe per-CPU buffers.

- Use ttynull as the ultimate fallback for /dev/console.

- Officially allow to disable console output by using console="" or
console=null

- Few code cleanups.

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

We believe that the risk of logbuf_lock removal is small.
It is another important step in the printk rework. We are
moving slowly and carefully.

----------------------------------------------------------------
John Ogness (2):
printk: inline log_output(),log_store() in vprintk_store()
printk: remove logbuf_lock writer-protection of ringbuffer

Lukas Bulwahn (1):
printk: remove obsolete dead assignment

Nikolay Borisov (1):
printk: ringbuffer: Reference text_data_ring directly in callees.

Petr Mladek (4):
init/console: Use ttynull as a fallback when there is no console
printk/console: Allow to disable console output by using console="" or console=null
