This is a note to let you know that I've just added the patch titled

printk: Avoid scheduling irq_work on suspend

to the 6.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...

The filename of the patch is: printk-avoid-scheduling-irq_work-on-suspend.patch and it can be found in the queue-6.18 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

This patch should be accompanied with the preceeding commit:

d01ff281bd9b ("printk: Allow printk_trigger_flush() to flush all types")

and the later commit:

66e7c1e0ee08 ("printk: Avoid irq_work for printk_deferred() on suspend")

in order to completely avoid irq_work triggering during suspend for all possible call paths.

Thanks, now both queued up.
