This is a kernel module (designed for Arch Linux) that generates process at /proc/count. When you type cat /proc/count, it prints the number of processes. To get the number, the module looks at the kernel's process table. This is a basic way to see some of what the kernel is doing.
make
sudo insmod proc_count.koThe C code is compiled into a kernel object file with the '.ko' extension. This kernel module is then loaded into the running Linux kernel. This will generate some output files, one of which should be proc_count.ko.
cat /proc/countThe expected output for this command is an integer indicating the current number of running processes in the /proc/count module. While testing, my result was 148.
sudo rmmod proc_count
make cleansudo rmmod proc_count removes the kernel module, while make clean cleans up build artifacts.
python -m unittestRunning this resulted in 3 tests being run in 8.684s, all passing successfully.
Report which kernel release version you tested your module on
(hint: use uname, check for options with man uname).
It should match release numbers as seen on https://www.kernel.org/.
uname -r -s -vThis command spits out the kernel version: Linux 5.14.8-arch1-1 #1 SMP PREEMPT Sun, 26 Sep 2021 19:36:15 +0000
