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-abdiel.janulgue@xxxxxxxxx/ 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/20241007202752.3096472-1-abdiel.janulgue@xxxxxxxxx/ Abdiel Janulgue (2): rust: page: use the page's reference count to decide when to free the allocation rust: page: Extend support to existing struct page mappings rust/bindings/bindings_helper.h | 1 + rust/helpers/page.c | 20 +++++ rust/kernel/page.rs | 135 ++++++++++++++++++++++++++++---- 3 files changed, 142 insertions(+), 14 deletions(-) base-commit: b2603f8ac8217bc59f5c7f248ac248423b9b99cb -- 2.43.0
