This is a single patch (v2) that adds `Send` and `Sync` implementations for `MapleTree<T>` in the Rust kernel bindings. The motivation is clear and well-documented: the C `maple_tree` struct contains a `*mut c_void` which inhibits Rust's auto-trait derivation, blocking downstream users like Nova's `Vmm` from satisfying the `Send` bound required by `pci::Driver`.
The approach is correct and follows established kernel Rust patterns — it mirrors `XArray`'s Send/Sync implementation almost exactly (see `rust/kernel/xarray.rs:272-277`). The `MapleGuard` is also properly made `!Send` via `NotThreadSafe`, which is important since the underlying spinlock must be released on the same CPU that acquired it.
**Overall: This patch looks correct and ready to merge**, with one minor nit below.
