atomic_t vs refcount_t in the Linux Kernel: Counters, References, and Object Lifetime Introduction When developing Linux kernel code, counters and object lifetime management can look deceptively simil
Understanding Linux Kernel Threads and Spinlocks
Introduction Concurrent execution is an important concept in operating systems and kernel development. Modern processors can execute multiple tasks concurrently, often across multiple CPU cores. When
Linux Kernel-Priority Inheritance
Introduction Priority inversion is a classic scheduling problem in real-time and concurrent systems. It occurs when a high-priority task is forced to wait for a lower-priority task, while a medium-pri
Linux Kernel Priority Inversion: Mutex, Scheduling and Priority Inheritance
Introduction Priority inversion is a classic concurrency and real-time scheduling problem in operating systems. The basic situation is simple: A LOW-priority thread owns a mutex. A HIGH-priority thre
