summary
Kernel development stays fast and concrete: about 15,000 changes per release from ~2,000 active developers with 200–300 new contributors each cycle, io_uring and data access monitoring gain traction, and mfd_secret syscall adds an in-kernel protected memory region. Real-time progress lands major work — sleeping spinlocks merged after 17 years (roughly 1,300 lines across ~50 patches, with ~1,700 lines upstreamed recently). Arm multi-platform generic kernels, Rust effort (~35k LOC out of tree), and real-world results like Mars Ingenuity: 29 flights running Linux show features are being built and used.
