Understanding Spinlocks in the Linux Kernel
In the world of operating systems, managing access to shared resources in a multi-threaded environment is critical to ensuring data integrity and system stability. The Linux kernel, being a preemptive multitasking operating system, employs several synchronization mechanisms to manage concurrent access to shared resources. One of the most fundamental synchronization primitives used within the Linux…
