BPF exception unwinds gain cleanup pads for Rust Drop
Yonghong Song’s bpf-next series makes bpf_throw() run compiler-emitted landing pads so resource-owning frames can release locks and values on the way out.

BPF gains indirect subprogram calls via new callx instruction
Alexei Starovoitov’s series lets the verifier and JITs accept LLVM’s function-pointer calls, unlocking vtables and dispatch tables in BPF C and Rust.
By oopsBPF exception cleanups unlock Rust Drop on bpf_throw() unwind
The kernel and libbpf now run compiler-emitted landing pads when bpf_throw() walks the stack, so frames can release RCU locks and other owned resources.

By oopsRust 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.
