android binder

Android Binder is the inter-process communication driver at the heart of Android, and this tag follows the proposal to retire its legacy C implementation in favor of Rust. The supplied coverage centers on Google's plan to make Rust the only upstream Binder driver for future Linux kernels, which would turn Rust from an optional alternative into a required toolchain for anyone enabling CONFIG_ANDROID_BINDER_IPC. That matters to Windows developers building Android platform images under WSL, maintaining Android Common Kernel trees, or supporting enterprise Android fleets, since the change marks a build and maintenance boundary as C Binder sources, Binderfs code, and C-specific allocator tests disappear.
