This series aims to add support for pages that are not constructed by an
instance of the rust Page abstraction, for example those returned by
vmalloc_to_page() or virt_to_page().
Changes sinve v3:
- Use the struct page's reference count to decide when to free the
allocation (Alice Ryhl, Boqun Feng).
- Make Page::page_slice_to_page handle virt_to_page cases as well
(Danilo Krummrich).
- Link to v2: https://lore.kernel.org/lkml/20241022224832.1505432-1-abd...
Changes since v2:
- Use Owned and Ownable types for constructing Page as suggested in
instad of using ptr::read().
- Link to v1: https://lore.kernel.org/rust-for-linux/20241007202752.309...
