Linux makes per-VMA locks unconditional across all configs
A series from Dave Hansen and Suren Baghdasaryan drops architecture gates so binder, TCP, and generic code can lock individual VMAs without mmap_lock fallbacks.

Rust Binder prepares to retire its C twin as kernel rewrites move past experiment status
Binder deletion, a Rust-only SPDM requester, and unconditional per VMA locks together shift the argument from whether Rust belongs in the kernel to what happens when a Rust implementation becomes the one that wins.
By kexecRust Binder parity makes C removal a real choice
A push to delete the legacy C Binder driver, a Rust SPDM requester for untrusted device auth, and unconditional VMA locks together force the kernel to decide whether dual maintenance ends in security-sensitive paths.

Google maintainers say the 15-year-old IPC code is too fragile to keep, and the Rust port is already shipping on Android.

The change lets binder and TCP drop mmap_lock fallbacks, and Andrew Morton has queued the series for testing.
