c-concurrency

C concurrency conventions: C11 atomics with explicit memory orders, C11 threads.h and POSIX pthread (mutex, condvar, rwlock, barrier), cache-line alignment to kill false sharing, ThreadSanitizer for race detection, and async-signal-safe rules for signal handlers. Use when designing multi-threaded data structures, debugging races/deadlocks, picking a memory order, or reasoning about lock-free patterns. Triggers on "原子操作", "memory_order", "TSan", "data race", "死锁", "条件变量", "false sharing", "pthread_mutex", "atomic_compare_exchange".
