Adding this to all pages would increase the memory footprint drastically.
Yea, that's a good point! Hrm... bummer. I'll have to see if there's some other way I can get the needed context for the free from the generic page-pool side.
What exactly is the problem here?
Me, usually. :)
As far as I can see we just have the lru entry (list_head) and the pool.
Yea, I reworked it to an embedded drm_page_pool struct, but that is mostly a list_head.
How the lru is cast to the page can be completely pool implementation specific.
Yea, I had it do container_of(), just haven't gotten around to sending it out yet.
Thanks so much for the feedback and ideas!
