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

 iommu/amd: Use put_pages_list

to the 5.16-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: iommu-amd-use-put_pages_list.patch and it can be found in the queue-5.16 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 would defer to Robin, but I don't think this is a good candidate for a stable backport. It has some dependencies, IIRC. And it's not really fixing a bug.

Indeed, I'd feel a bit uncomfortable about backporting this unnecessarily. It doesn't make much sense in isolation without the other patch(es) converting the rest of the IOMMU subsystem as well, but either way unless the whole SLAB rework needs backporting for some reason then it just represents risk without benefit.

Thanks, Robin.
