Linux Kernel: Create a Loadable Kernel Module to add a new file into /proc (proc filesystem)
One of the most significant features of the Linux kernel is the way it exposes lots of interesting statistics via /proc filesystem ABI. In this short video, we will explore the easiest way to expose the kernel jiffies variable to user-space using the procfs API (within the kernel). This should provide enough guidance for newbie kernel developers to leverage procfs to expose stats of their own device drivers / subsystems.
