Linux Kernel Developer Panel
summary
Panel reports concrete work: Kselftest consolidated tests and four new syscalls each with a man page and a test shipped; syscall auditing once crashed machines on some arches and those bugs are fixed; namespaces keep revealing subtle security holes as adoption grows; effort to shrink kernels for tiny devices cites Raspberry Pi as a seed; ARM merge workflow and cross-build testing improve but hardware access remains scarce; persistent cruft like tasklist lock, mmap_sem and huge TLB/page complexity still need redesign; occasional compiler/linker miscompiles and an AMD identity‑map race were tracked down and corrected.
