TBH sounds like weird piece of HW. IDK if we want to burden the generic page pool code with weird, 20+ yo drivers+HW :/ Well, I know that I definitely don't, I don't know if others agree :) Looks like AI has found plenty o'bugs. Also, please never put Fixes tags from Linus's tree on net-next patches. Either net or not a fix. -- pw-bot: cr
