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

ext4: convert ext4_da_do_write_end() to take a folio

to the 6.6-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: ext4-convert-ext4_da_do_write_end-to-take-a-folio.patch and it can be found in the queue-6.6 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.

I'd think you'd want to backport 83f4414b8f84 to before folios existing, so you may as well use the same patch for 6.6 as you'd want to use for those older kernels. ie:

if (unlikely(!page_buffers(page))) { unlock_page(page); put_page(page); return -EIO; }

but maybe this has already been discussed and I wasn't cc'd on that discussion.
