C Fundamentals for Kernel Engineering: Mastering Concurrency, Memory, and Performance Optimization in Modern Kernel-Level C

From the first line of code that touches page tables to the last atomic instruction guarding a lock-free queue, this definitive guide lifts the curtain on exactly how professional kernel developers write, debug, and harden C at the heart of every modern operating system. It condenses years of real-world expertise into a relentlessly practical reference packed with production-grade patterns, compiler wizardry, and concurrency strategies you can drop straight into your own low-level projects.

- High-Performance Memory Mastery - page allocator APIs, NUMA-aware placement, zero-copy buffers, and cache-line padding techniques that squeeze every cycle from today's multicore CPUs.
- Rock-Solid Concurrency Toolkits - spinlocks, seqlocks, RCU, atomic operations, and preemption control woven into hands-on examples that stay fast and deadlock-free.
- Cutting-Edge Optimization Secrets - branch prediction hints, static keys, jump labels, and compile-time assertions used by top-tier maintainers to ship code that never slows down.
- Lock-Free & Wait-Free Algorithms - build ultra-scalable stacks, queues, and ring buffers with detailed, step-by-step reasoning about memory ordering and data-race safety.
- Instrumentation & Observability - tracepoints, eBPF helpers, and live-patch-safe patterns that turn production kernels into live laboratories-without compromising performance.
- Secure, Future-Proof Engineering - integer overflow guards, sanitizer annotations, and hot-patch-ready data access strategies that make your code resilient to both bugs and CVEs.

Each of the 99 laser-focused chapters drills into a single cornerstone concept-just enough theory to ground you, then straight into listings, idioms, and battle-tested checklists that stick.

- Systems programmers advancing from user-space to kernel-space.
- Embedded engineers chasing deterministic performance on constrained hardware.
- Security researchers auditing close-to-metal C.
- DevOps professionals exploring eBPF observability and live patching.
- Computer science students seeking a career-ready jump start into operating-system internals.

If you're comfortable in C and hungry for the power that lives beneath libc, this book hands you the keys.
