[PATCH 0/2] rust_binder: charge allocated pages to memcg

[Alice Ryhl]

Pages allocated by the Rust Binder driver and mapped into a process's
VMA are currently not accounted to any memory cgroup. Add
`Page::alloc_page_memcg()` (using `put_page()` on drop so folios are
uncharged when freed), and use it to charge newly allocated binder pages
to the target process's `mm_struct`.
